Tinning(redirected from tin-plating)
Also found in: Dictionary, Thesaurus, Wikipedia.
the deposition of a thin layer of tin on the surfaces of sheets, strips, wires, and other articles and semifinished products made chiefly of metal (steel and copper).
Metals are tinned to protect them from corrosion. In one tinning method the article is immersed in molten tin and in the other method the tin is deposited on the surfaces by the passage of an electrical current through the bath with an electrolyte in which the article is immersed. The inner surfaces of vessels used to preserve food products are tin-plated, as are the surfaces of certain machine parts and other items.
