Chrome plating

Short description

Chrome plating is a widely used electroplating process when coating iron and its alloys. Single-layer chromium coatings are very porous even in thick layers, and therefore such chromium plating for corrosion protection can be carried out only after the application of intermediate layers of other metals, for example, copper, nickel, on the surface of the product. The process of such a multi-layer coating is called protective and decorative chrome plating. Decorative chrome plating is widely used to cover the outer parts of machinery, appliances and household items.

The industry also uses the process of hard chrome plating, i.e. plating with chrome in order to increase the surface hardness and resistance to wear of tools, rubbing parts of parts, etc. crankshafts, etc.). Experience has shown that hard chrome plating increases the service life of steel products by 10-30 times. Unlike protective and decorative, hard chrome plating is carried out without applying intermediate layers of other metals.
