Comments Off on Five Advantages of Electroless Nickel Plating


Electroless nickel plating offers an enormous range of benefits. Results that cannot be attained in the electrolytic nickel plating can be achieved easily in this process. The reason behind this is the nature of the process.

 

In electroless nickel plating, a substrate is dipped into the bath of plating solutions, and this solution triggers a chemical reaction that deposits the nickel layer on the substrate. No electricity is required in this process. It is a purely chemical based reaction. A reducing agent drives the nickel to the surface of the substrate and forms a uniform layer on the substrate.

Electroless nickel plating has numerous advantages. Let’s have a look at a few key advantages of this process.

Uniform deposition

When it comes to the metal coating of the irregular and complicated shaped workpieces, electroless nickel plating is best in the business. It is very difficult to achieve the uniform thickness of metal layer all over the substrate with electrolytic nickel plating. But with electroless nickel plating, the thickness of the metal layer deposited is even over the entire surface of the substrate.

Higher Corrosion Resistance

This is the major perk of electroless nickel coating. This coating is less porous and uniform throughout the workpiece. Hence, it provides high corrosion resistance. The thickness of the metal layer deposited can be as thin as .0005″ to as thick as .010″. This great control over thickness makes it a perfect choice for various industries. It can be used for the metal coating of the rotor, drive shafts, oilfield valves, fuel rails, kitchen utensils, bathroom fixtures, and other similar materials.

Cost-effective

Another major advantage of electroless nickel coating is that it is cheaper than the electrolytic nickel coating. There is no electricity required and no extra cost of finishing required which makes it a cost-effective coating process. Also, due to improving coating quality operational cost is less.

Wear Resistance

Electroless nickel plating does not chip off easily. It is baked to harden to 60+ Rockwell. It is strong and chip free coating. You do not have to worry about the strength of the coating.

Non-conductive Material Coating

As no electricity is used for depositing the metal layer to the substrate, therefore, it can be used for coating non-conductive material. A wide range of products and materials can be coated using this coating.

These are the key advantages of the electroless nickel plating.

If you are looking for a uniform, consistent, and long-lasting metal coating for the workpieces, no doubt electroless nickel plating is best of the breed.
