Chrome plating is an increasingly popular means of providing an enhanced look, durability, and protection (from corrosion specifically) to metal components. Chrome plating is found on many parts such as automotive parts and industrial machinery and is essential for improving the performance and appearance of many components. If you are thinking about using chrome plating on your project; here is what you need to know.
What is Chrome Plating?
Chrome plating or chromium plating is the process of electroplating a thin layer of chromium onto a metal surface. Each metal component to be plated is immersed into a chemical solution, and an electric current is then passed through the chemical solution to bond the chromium to the surface of the component.
Once completed, the component will have a smooth, shiny, and high-quality finish which resists wear and tear due to corrosion or other environmental exposure.
Types of Chrome Plating
Chrome plating is performed in many different ways depending on whether the plating is intended for decorative or industrial use. The two common methods of chrome plating are;
1. Decorative Chrome Plating
Chrome plated products offer an attractive “mirror finish”, serve as a decorative finish and provide a shallow degree of corrosion protection. Chrome plated products are commonly produced for automotive trim and wheels, motorcycle parts, bathroom fixtures, furniture accents, etc.
Chrome decorative coatings are usually applied over existing layers of nickel and copper to increase their shine and improve their durability against corrosion.
2. Hard Chrome Plating
Hard chrome plating, or Industrial chrome plating, will add strength and durability to your product beyond just providing a decorative finish. Hard chrome plating is much thicker than decorative coatings, and is typically applied directly to metal substrates. Some common applications for hard chrome plated parts are:
Hydraulic plungers and rods; shaft for commercial and industrial applications; tooling and die components; components in from heavy machinery.
Hard chrome plating improves the performance of critical components by increasing their ability to resist wear, resisting friction, and dramatically increasing the usable life of the product.
Benefits of Chrome Plating Services
Chrome plating provides both visual and functional benefits to metal components, increasing their longevity and quality. Benefits include:
Increased Durability – Increasing the ability of a component to resist wear and tear.
Corrosion Resistance – Protecting the metal from rust and environmental damage.
Improved Appearance – Producing a beautiful, polished surface.
Low Friction Surface – Providing a great surface for mechanical components that require movement.
Easy Maintenance – Smooth surfaces are easy to maintain and clean.
Chrome plating is used in the Automotive, manufacturing, aerospace and marine industries; therefore, giving the manufacturer a strong desire to use chrome plating as the finish of choice.
The Chrome Plating Process
Electroplating of chrome is usually accomplished through a very thorough preparation and finishing process to produce a durable and high-quality product. The specific steps of this process may differ somewhat from facility to facility; however, there are generally about four necessary steps for successfully completing the electroplating process, as follows:
- Surface preparation (cleaning and polishing)
- Pre-treatment and base metal coating (if required)
- Electroplating with chromium
- Final polishing and quality inspection
The importance of proper surface preparation cannot be stressed enough; it is one of the most critical factors in achieving an excellent finish and optimum adhesion.
Choosing the Right Chrome Plating Service
The importance of proper surface preparation cannot be stressed enough; it is one of the most critical factors in achieving an excellent finish and optimum adhesion.
- Experience and technical expertise
- Quality control standards
- Turnaround time
- Compliance with environmental regulations
- Capability to handle custom or industrial-scale projects
These factors alone will help ensure that your chrome-plated parts will have a consistent level of quality, durability, and dependability.
Final Thoughts
Chrome plating can add more value than cosmetic enhancement; it also adds performance, extends the usable life of the part, and adds a professional appearance to the component. Therefore, by utilizing the proper chrome plating solution, you are enhancing your parts with respect to both value and reliability, regardless of whether you’re using chrome plating as a decorative finish or as an industrial-grade protection.
Businesses that are utilizing 3D printing services in Australia are able to apply chrome plating to certain 3D printed items to provide some extra durability, strength, and aesthetic appeal (automotive, industrial and display).
If you want to add durability, performance, and appearance, chrome plating remains one of the most trusted forms of surface finishing options today.
