Electroplating is the technology of depositing metals from solutions onto metallic surfaces by electrolysis. The resulting coating is tightly bonded to the surface and is mineral in nature. Coatings may be used to protect against oxide formation (rust) on base metal surfaces, to assist in electrical conductivity, and in decoration.

ZINC
Zinc plating has been the most popular choice for corrosion protection, due to its low cost. The move to provide higher quality and longer lasting finishes has resulted in a shift to more use of alloy zinc deposits – especially in the automotive, aerospace and electrical industries.
