Electroplating - The Full Wiki

Electroplating is a plating process that uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal. Electroplating is primarily used for depositing a layer of material to bestow a desired property (e.g., abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc ...

What is ELECTROLESS NICKEL

Apr 14, 2015 · Simply put, one of the big advantages of electroless nickel is the even coating of all surfaces. With electrolytic plating, the current (and plating ions) go to the highest points and the edges. Inside surfaces get little coating and edges get more. Electroless coats everything evenly, without buildup that is uneven.
