In this section you can find some technical articles about surface coatings and precision mechanics.
Difference between electroless Nickel Plating and Electroplated Coatings Electroplated coatings (such as chrome plating, electroless nickel plating, zinc plating, zinc-nickel plating) are deposited by applying direct current to the part, which allows the metal to be deposited on the surface of the part to be coated.

Electroless nickel plating is commonly applied successfully to all aluminum alloys. Its uniform thickness, corrosion resistance and high hardness are an efficient barrier against corrosive agents and situations where wear plays an important role.

One of the main properties of electroless nickel plating is its corrosion resistance. Electroless nickel plating is in fact used on mechanical metal parts (steel, aluminium alloys or copper) when protection from oxidation and corrosion by external agents is required.
