What is Zinc Plating?
Zinc is a lustrous metal; hard, crystalline and brittle, which is blue white in colour. Zinc plating involves the electrolytic application of zinc by immersing clean steel parts in a zinc salt solution and applying an electric current. When zinc plating is applied it is almost always deposited in the fully bright condition which provides an attractive finish, yet still provides excellent corrosion proofing; including rust-proofing on iron or steel. Zinc can act as a base for further treatments and can be passivated in order to extend the zinc resistance.
Benefits of Zinc Plating
Zinc plating is the method of choice for being a low cost form of electroplating, generally applied to ferrous components to offer corrosion protection. Zinc plating is an attractive finish providing a bright, smooth service. Components that have a high tensile strength need to have a subsequent hydrogen de-embrittlement process carried out. This type of plating also offers a low stress deposit, superb chromate conversion coating receptivity, exceptional ductility and adhesion.
Applications of Zinc Plating:
- Commonly used on nuts, bolts, metal brackets etc.
- Makes an excellent undercoat for paint or powder coating
