The Magic of Metal Plating

Metal plating is a complex process that coats surfaces with metal atoms, enhancing both performance and aesthetics; it works on many different kinds of surfaces.

Examples of metals used in metal plating are silver and gold; not only for appearance, but also to provide strength, corrosion protection and electrical conduction.

This article gives an overview covering the applications and benefits of metal plating.

What Is Metal Plating?

Metal Plating

Metal plating coats metal surfaces with other materials and enhances aesthetics or corrosion resistance. However, the method works on many materials. Examples of materials that can be plated include brass, copper, steel, aluminum, and iron; the process deposits a thin layer on top.

Electroplating is a popular method. An electrical current attracts charged metal ions and they move towards a negatively charged metal surface.

Needless to say, this process not only forms a uniform plating layer for aesthetics and durability, but also improves heat dissipation properties.

Metal plating can also act as an electrical conductor improving the conductivity of the treated item.

Examples of plating such as zinc, chromium, nickel and cobalt suit a variety of applications and product needs with the choice depending on their purpose.

Overview of Metal Plating

Different Types Of Metal Plating

Metal Plating Types

Many methods exist for metal plating. Some need electrochemical items like an electric current and electrolyte fluid. Others use physical brushing and abrasive metal painting techniques. Let’s explore common types you may encounter.


Electroplating is an old method that uses an electric current to deposit a thin coating. A metal fusion plating, is an electronic attraction forms between two materials.

Gold and nickel are examples. When various metals are used as coatings, a reaction occurs when exposed to electricity. Gold and metal chrome plating are popular in automotive and jewelry industries.

An all-inclusive metal plating kit is helpful as it contains materials and chemistry to remove contaminants. Some processes need four different solutions for the bath, and special items ensure a successful result.

Electroless Plating

Electroless Plating technique needs no external electric source and the reaction happens in an alkaline solution with other components.

Particles of a chosen metal bond form deposits on the base layer and a protective metal plating layer is also created.

Moreover, this method is used for engineering, military, and industrial components providing a hard coating that resists pressure and heat.

Decorative finishes are also possible, adding color and finishing touches. Nickel and various alloys can be used. Commercial and decorative applications are adaptable.

Immersion Plating

Immersion plating submerges a material in a solution tank, which is similar to electroless plating but more efficient and costeffective. No external electrical current is needed.

Immersion plating is a popular technique in the military and aerospace sectors as it prevents corrosion and wear, making it ideal for bulk production with minimal time and cost.

Vacuum Plating

Vacuum metal plating is unique and uses vacuum pumps as well as chambers. Certain materials are heated until partially evaporated. At this stage, desired material atoms scatter.

As they bind to particles in the vacuum chamber, a base layer forms from this process. Also, such method is perfect for uniform coverage and works for parts needing large thickness amounts, with additional advantages.

Vacuum plating has many applications in industries such as aerospace, motor-sport and decorative.

Barrel Plating

Barrel plating is a method using barrels, chemicals and specific pieces in an endless process with small cycles that take place within tanks.

Cylinders turn, introducing diverse materials and platings. Alternating steps create a consistent finish that works for items like PCB substrates and jewelry.

Barrel plating needs an external electric current, which is used for items too large for dip tanks.

Setup times are extensive as parts stay stationary inside the barrel, not moving or rotating to avoid interference.

Brush Plating

Brush plating is a useful concept to reach hard-to-reach applications. Electric current is introduced into tiny brushes. Carbontipped tools create contact with the desired layer, and metal atoms or particles are introduced.

Uniform coverage is achieved on any given part and it‘s handy for specific finishes on difficult shapes, enabling plating items in certain locations.

A fast turnaround time is possible. Brush plating systems come in various sizes and shapes, although they are more expensive but offer stainless steel design.

Continuous Plating

Continuous metal plating is not common, but the process involves an endless item supply entering the plating bath.

Time and money are saved by uniform results with minimal setup times needed, making it ideal for use in large manufacturing processes. Consistent coating of large quantities is achieved, and technical information is important for success.

Accurate notes on cycles, temperatures, and concentrations are needed. No interim inspection or extra finishing steps are required.
