Electroless Nickel Plating Process vs Electrolytic Nickel

The electroless nickel plating process (EN) has several distinct advantages over the traditional electrolytic nickel plating process. The primary difference with the nickel plating process is that EN does not require the application of an external electrical current to drive the deposition as does electrolytic nickel.
