Abstract
A method and apparatus for coating a substrate (4) with a metal coating by vaporizing the metal in an enclosure (1) containing a selected gas and the substrate. The vaporized metal is deposited on the surface of the substrate either in a solid or molten form depending on the temperature of the substrate relative to the melting point of the metal being deposited. Alloying of the substrate and coating metal are possible with various postcoating heat treatments.
