Nickel plating has become quite famous in CNC machining for a huge range of products. Nickle plating not only enhances aesthetics but also increases the strength, hardness and durability of a part. It has a unique combination of high functionality and aesthetic appeal which attracts many manufacturers. In this article, we will explore the process, types, advantages of nickel plating, and applications of nickel plating parts.

What Is Nickel Plating?

Nickel plating is an electrochemical process that protects the part from corrosion, improves wear resistance and decorative appearance of a part. It also builds up the worn parts.

Introduction of Nickel Plating

A metal part is sunk in an electrolytic solution which has nickel ions and electric current in applied. This current creates a uniform layer of nickel deposited on the substrate. There are two common types of nickel plating which are electrolytic plating that uses current and electroless plating. This uses an auto-catalytic chemical process to deposit nickel onto a substrate without the current. The coating produced from this method is more uniform and can be applied easily over complex shapes.

Nickel Plating vs. Anodizing

Nickle plating is an electrochemical process depositing nickel onto a substrate. While in anodizing natural oxide layer of metal is thickened through an electrochemical process. The main difference between them is material compatibility. Anodizing is limited to aluminum, and sometimes to titanium and magnesium while nickel plating can be carried out on many metals like steel, copper, aluminum etc.

Types of Nickel Plating

Nickel plating can be divided into two main types, electrolytic and electroless plating which are further sub-divided into more forms. These are explained below:

Electrolytic Nickel Plating

As mentioned above, electrolytic nickel plating uses electric current to deposit nickel onto the substrate. The types of electrolytic nickel plating are:

Bright Nickel Plating
