Hard chrome plating is a specialized electroplating process that deposits a thick layer of chromium onto a metal surface to enhance its durability, wear resistance, and corrosion resistance. This process, which involves the use of a chromic acid solution, has become a go-to solution in various industries where component longevity is essential. WWG Engineering offers top-notch hard chrome plating services, with state-of-the-art facilities and plating tanks capable of accommodating both small and large components. Their advanced setup ensures that every part, regardless of size or complexity, receives a high-quality chrome coating to meet specific operational needs.

The Hard Chrome Plating Process

Hard chrome plating is distinct from decorative chrome plating. While decorative chrome is typically applied in thinner layers and is primarily used for aesthetic purposes, hard chrome is applied for functional reasons—mainly to increase the lifespan and performance of machine parts exposed to harsh environments. The thickness of hard chrome plating can range from 25 to 1,000 microns, making it a highly versatile solution for numerous industrial applications.

The process starts by immersing the metal component into a chromic acid solution, where chromium is electro-deposited onto the surface. Electro-deposited chrome is known for its incredible hardness, with typical values ranging between 850 and 1050 HV (63 to 70 HRc). These hardness levels make hard chrome one of the toughest and most durable coatings available, hence the term "hard" chrome.

Key Benefits of Hard Chrome Plating

The advantages of hard chrome plating go beyond its impressive hardness. Here are several key benefits that make it ideal for various industries:

Increased Wear Resistance: Hard chrome is exceptionally resistant to abrasive and erosive wear due to its high hardness and low coefficient of friction. The coating is capable of withstanding repeated contact and movement, making it perfect for components exposed to friction-heavy environments.

Enhanced Corrosion Resistance: Hard chrome offers excellent resistance to atmospheric oxidation, preventing the metal underneath from corroding. Its ability to withstand both oxidizing and reducing agents makes it a top choice for components that operate in corrosive environments.

Self-Lubricating Properties: One of the lesser-known features of hard chrome is its self-lubricating properties. This characteristic reduces the need for external lubrication in some applications, improving efficiency and reducing maintenance costs.

Thermal Stability: Hard chrome is considered a "cold" plating process because it operates at temperatures between 50 and 60°C. This ensures that the physical and mechanical properties of the base material are not affected during the plating process, making it suitable for a wide range of materials and applications.

Repair and Salvage Capabilities: In addition to improving the performance of new components, hard chrome plating is commonly used for salvaging and repairing worn, damaged, or mis-machined parts. Thicker deposits of chrome can restore these components to their original dimensions, allowing them to be reused and extending their operational life.

Common Applications of Hard Chrome Plating

Given its excellent wear resistance, corrosion protection, and other beneficial properties, hard chrome plating is widely used across a broad spectrum of industries. Among the most frequent applications are:

Hydraulic and Pneumatic Piston Rods and Cylinders: Hard chrome plating helps reduce friction and prevent wear on moving parts, extending the life of these critical components.

Molds, Dies, and Screws: In industries like plastic injection molding and die-casting, hard chrome improves wear resistance, helping molds and dies maintain their accuracy and prolonging their service life.

Print Cylinders and Plates: The smooth, hard surface of chrome-coated print cylinders ensures high-quality printing while resisting the wear and tear associated with high-speed printing operations.

Valves, Gates, and Bodies: The corrosion-resistant and wear-resistant properties of hard chrome make it a reliable solution for valves and gate bodies that operate in challenging environments, such as the oil and gas industry.

Mining Equipment: Hard chrome plating is commonly used to extend the operational life of mining equipment exposed to harsh conditions, including abrasive materials and corrosive environments.

Pump Shafts and Rotors: In the pump industry, hard chrome plating ensures that shafts and rotors maintain their dimensional integrity and resist wear, even in environments with high friction and pressure.

Conclusion

Surface engineering is a comprehensive, facilitating activity that calls for meticulous expertise. Comprising of surface modification techniques and processes, producing diverse as well as combined material surface properties to address the challenging requirements, surface coating or surface engineering is practically employed in various industrial sectors and individual clients.

The processes are carried out by applying a protective film of materials or its alloys in order to safeguard the outer surface of a material from getting spoilt by external hazards like rusting, corrosion and other weathering actions that may prove to be disastrous to the material itself. These techniques are mainly based on coating of synthetic polymers, which are nothing but industrially produced elements containing large, interconnected molecules that make a strong but yet flexible, films on the material surfaces. Similarly materials like pigments also constitute surface coatings, which are used in case of materials which require the retaining of colour, glossy finish, opacity, and so on. To enable the easy application of these pigments or colours, a suitable solvent or solvents or carrier liquids, are incorporated into it in order to facilitate a paintable or applicable liquid medium, thereby providing a host of properties and advantages.

Chemically these polymer-based coatings that are applied on the material surface are considered to be a mixture of composite materials mainly consisting of a pigment or coloured particles which are disseminated in a solution of a suitable polymer. Owing to its chemically active property of resistance and flexibility, which supplements its adhering to the substrate, polymers provide and excellent coating over the materials surface.

Since these polymer based coatings have certain speciality qualities like, durability, glossy nature, and resistance against weathering actions, they make a very good surface coating which is reliable and long lasting. Surface coating is also carried out y one more popular and reliable method, that is powder coating. In this method, the material surface is coated with a shower of pigmented or coloured polymer particles, which are then bonded on to the surface by heating, which thereby forms a continuous thin film which acts as a protective sheet or layer on the material surface. Although reactions may take place throughout the heat induced melting of particles and adhering or fusing, the major aspect of film is the formation of the protective coating.

WWG Engineering Pte Ltd located in Singapore has been an integrated one-Stop engineering solutions and services. Blended with a distinctive and specialized technology, and an equally knowledgeable engineering backing, WWG Engineering is undoubtedly a pioneer in the area of engineering equipment and component machine refurbishment services and repairing.

Developed with intent to protect the material surfaces from weathering actions, corrosion, surface degradations and so on, the technique of surface protection, (which otherwise in common language is referred to as surface engineering), is the simple modifying, of a metal surface or any other surface. Enhancing the material surface properties methodically, surface engineering has an important role to play in the protection of material surfaces that are vulnerable to external factors. The main concepts behind surface engineering are modification of the surface without affecting the material composition, modification of surface involving compositional adjustment and the direct application of coatings of suitable materials like pants or alloys on to the surface, where in no physical or chemical changes or alterations are done. While there are other processes of protecting the surface materials by transformation like hardening, surface texturing, carburizing, nitriding, anodizing, electroplating, hard-facing, thermal spraying and vapour deposition, all the techniques however aim at the protection of the material surface. Although surface engineering has been widely applied in various sectors along-side there has been quite bit of research activities that has been carried out in order to improvise it. Setting up of the surface engineering research institute, bringing out the international journal of surface engineering, has given scope for developing of the sector rapidly in recent years. In the recent two to three decades, surface engineering has virtually gone through swift developing stages, from the traditional single coating technology to composite surface coating technology and nano surface technology.

The growth of nano science and its technology, use of nano-materials and nano-technologies have been made use in surface engineering. In the recent time surface engineering techniques are being utilised in sports good manufacturing. The capability of creating diverse and collective surface properties, the technique efficiently meets the challenging design requirements needed in the advanced sports merchandises. Surface engineering technologies thus has initiated application in the sports equipment sector and has undoubtedly created a very strong impact in the sport equipment designing and development.

All put together, surface engineering is such a technology that targets at the adjustment of microstructure, composition of the surface region, in order to improvise the surface-dependent industrial properties of the material and its surface. However this requires a lot of technical expertise and enormous amount of knowledge and technical know-how. Organizations like wwg engineering have been in this sector since long. They possess the required skill sets, technical expertise, dedication and above all the grit to satisfy the clients by giving them the best services. Wwg engineering offers all the compositional surface engineering technology services in the most economical and convenient ways.

Collectively comprising of numerous surface coating and surface modification techniques and processes surface engineering collectively is a wide ranging and analytic technology. The technology basically is capable of creating a diverse set of surface properties to make the challenging requirements of users and is considered as the most suitable solution. The basic reason for the modification of the surface structure of the material surface is to protect it from atmospheric, chemical, or any other accidental actions, which may otherwise destroy the entire material. While there has been various methods and technologies that have been used to carry out this particular action with advancement of science and technology the methods procedures and processes have also been upgraded along with the use of sophisticated devices and equipment.

The protection of material surfaces was initially carried by employing very simple methods like coating metal surfaces with agents like paint, red oxide or chromium. While paint and red oxide application was done manually using a brush or roller, chromium has to be done by a chemical method known as electrolysis, where, in the material, which had to be coated with chromium would be used as one of the electrodes. Spray painting was an upgrade of simple painting technique, where the paint would be brought to lower consistency and would be sprayed on the surface using a spray gun. Here the application of paint on the surface would give a smooth finish, and totally eliminate streaks and craters, that would otherwise be created with a brush or a roller. However, this method also had its disadvantages. The first and foremost one was the chipping of paint, which would occur if the paint could not adhere to the metal surface or other material surface. 

So, in other words this method was not a permanent method of protecting the material surface. In the recent years surface engineering with an increasing demand has also updated into advanced scientific methods like plasma, treatment, and so on. While there are cases where in surface engineering methodologies are employed to protect the surface of material likewise, there are cases where in properties of metallic and non-metallic components or surfaces are altered for decorative purposes also. Another very commonly used method to protect metal surfaces that are used to make cabinets, shelves and similar items is that of powder coating. In powder coating, a spray of fine quality powder of the desired colour is sprayed onto the surface thereby creating a protective layer. Engineering specialists like WWG who are the pioneers surface engineering techniques are constantly looking up for highly sought after technologies in this field, by combining integrated engineering services offering diverse facilities in mechanical engineering services, water, treatment, power generation marine and petro chemical sectors.

Generally the process of surface engineering involves the modifying the surface of the material surface, in order to protect the surface and the material from external actions such as corrosion, rusting etc. due to exposure to harsh weather, chemical spillage, humidity and so on. This modifying may be done in many ways which are suitable and favourable with respect to the material surface, and varies with the utilities that the material may be used for. Although there are quite complex ways involved, in general the most common method is by applying a coating of a suitable material such as paint, chromium and so on. While the coating of paint is the most simple method where the liquid is applied through a brush or a sprayer, the coating of chromium and other alloys require a bit more complex methodology called electroplating, in which the electrodes are replaced by the material to be coated.    Other sophisticated methods that are followed are chemically altering the material surface, by revealing the material surface to high-energy ions. This methodology is made use of in plasma action of tissue culture polystyrene, which in simple sense is deposition of a thin film of the material with the preferred properties on the material surface. This method is used for the reason that it is comparatively simple, but however its use is limited due to the dependency on the initial properties of the material surface. While another method offers improved tractability because of the wide range of thin filming, this apparently can be tweaked expending diverse inter-actions, thicknesses and handling conditions. Nevertheless, these processes that are employed to carry out the modification of material surface by the applying of thin films of alloys or other suitable coatings are made use of in a range of industrial applications, which include fortification of cutting tools, complex optical devices and microelectronic sector.

The crucial aspect that the coating depends on is the physical and chemical attributes of the metal surface and the material used for the coating. All the same, various process parameters are attuned to regulate the film application on the surface, which basically include rigidity, refractive index, and endurance of the material surface. All the same the surface materials exhibiting properties like resistance, transparency and opaqueness and so on pay a major role in a specific way, and this aspect has led to the drastic expansion in this sector. Hence, the concepts of surface engineering have advanced in recent years, because the demand for improvisation of surface materials has also augmented. Organizations like WWG engineering, Singapore, are engineering equipment and surface coating specialists. With the extensively competitive market, WWG Engineering Pte Ltd constantly look for highly sought-after technologies to create a integrated engineering services competency.

The concept and the practice of surface engineering has been said to have undoubtedly extended in the last few years owing to the rapid increase in the mandate for improved materials surface enhancements. This increase in enhancement has made way for any possible progressions that can be worked out meticulously. Generally materials show bulk properties such as elasticity, transparency or opaqueness, hardiness, etc. and in some case the interaction with external systems as well.

An increase in the surface area of materials makes surface engineering even more important as the demand for an increased size and volume calls for more. However, implementing the methods of surface engineering needs technical knowledge and skill, which can be categorised into two main groups, the method of coating a surface by suitable metals or its alloys, painting the surface to avert any chances of corrosion. Coating the material surface with a fairly thin film of the alloy or any other suitable metal, comprising of the preferred properties is actually done by electroplating methodology which is an old and proven method.

Although the method of painting is used quite extensively, the application is limited owing to the initial properties of the material surface. The other method of electro plating is quite popular because of  the flexibility of the coating metals and the thickness of the film can be checked and controlled according to the requirement. With increase in the number of demands that the material surface must satisfy after the application, also proportionally tends to increase of a much deeper knowledge of how the material surface reacts with the action that is executed and the change in the properties of the metals and its resultant effect.

In this respect there are a few companies who are exerts in the surface technology. One such is the WWG engineering in Singapore. The company with the incorporation in January 2012 entered the competitive market as an engineering services provider, with expertise in advanced and state of the art surface engineering technology.
