Electroless Nickel Plating

Electroless nickel plating (ENP of NiP) is a response that deposits a nickel-phosphorus alloy onto the surface of a metal. It utilizes a totally chemical reaction to generate plating and does not take advantage of electrical power. Though this process takes much longer than electroplating, benefits are a more consistent thickness over even one of the most complicated surface areas (because of not having to rely upon differing electrical areas), in addition to remarkable wear and deterioration resistance.

Electroless Nickel Plating Parts

Electroless Nickel Plating Process

Electroless nickel plating is a wear, abrasion, and rust-resistant coating that is compatible with aluminum, stainless steel, and light steel.

Here’s how to apply electroless nickel plating:

Components are first washed and degreased to eliminate any kind of impurities, cleansing away any oil or oil.
After cleansing is finished, the substratum is turned on with another chemical, an acid, to eliminate oxides and trigger the surface area.
Components are dipped in the plating chemical service, transferring the nickel-phosphorus alloy on the components till the desired density is reached

Electroless Nickel Plating Design Considerations

Masking: Electroless nickel plating does not have a significant dimensional impact, therefore masking parts is not necessary.

FAQs

1. What is electroless nickel plating in CNC machining?
