Electroless Nickel Plating

Electroless nickel plating is a process that enhances the life of parts, particularly made from steel. It chemically reduces currents of nickel ions in a special solution. Nickel metal is used in this process for plating without utilizing electrical currents.

Electroless Nickel Plating Features

Electroless nickel plating is desirable because it leaves deposits that are uniform in thickness. This is due to its excellent corrosion resistance and high hardness. You will not need to worry about excess build up at corners or edges of parts with this process.

In this process, the main contributor in reducing nickel ions is a chemical reducing agent in the plating solution. The agent is practically constant at all points of the component's surface. The agitation should ensure a uniform concentration of reducing agents with the nickel metal ions.

There are many notable advantages to electroless nickel plating. It is advantageous in plating objects with an irregular shape, such as misshapen holes, valves, internal surfaces, recesses, or threaded parts. Deposits are also harder and less porous, so it provides barrier corrosion protection that is superior to other metals.
