Electroless Nickel Plating Explained
Electroless nickel plating, often referred to as (EN), is a process used for depositing a nickel alloy onto a substrate or surface without the use of electrical energy. Unlike electroplating, which does require a charge, the electroless nickel plating process involves submersing the substrate in an aqueous solution that contains a chemical reducing agent which acts as a catalyst for reducing the ions in the nickel deposit. The reduction process generally can use a few different agents to achieve its goal. However, sodium phosphite is used in over 95% of all EN plating.
Electroless Nickel plating is extremely versatile and reliable.
Unlike electroplating, EN plating produces an even application that impedes build up on the substrate. This build up often times require post process grinding to even out the surface. EN plating avoids this as it produces an even plating thickness which is crucial for achieving specific tolerances.
Additionally, EN deposits are often less porous than those of electroplating or hard chrome. This provides a superior corrosion barrier making electroless nickel plating especially beneficially for plating irregular items or parts that have recesses, internal surfaces, threaded parts or valves.
Because of it’s exceptional resistance to corrosion and the metals high hardness, electroless nickel plating can be used in a wide variety of applications such as on parts that will be exposed to severe conditions such as that of the aerospace and defense industries.
