Abstract
A conductive electrode wire is passed through a molten salt bath maintained at a temperature above the melting point of the salts. A main electrical power supply passes an electric current between the electrode wire and an anode in the molten salt bath so that a metal coating layer is electrolytically deposited onto the core of the electrode wire. The high temperature of the molten salt bath ensures inter-diffusion of the metals of the core and the coating. This enables diverse coating structures to be obtained by choosing electrolysis and diffusion parameters.
