ABSTRACT A method for forming an anticorrosive coating on the surface of a metal substrate, which comprises, (1) coating a surface of the metal substrate using a spraying procedure with an anticorrosive metal capable of forming an alloy with the substrate metal; and (2) heating the coated surface in a vacuum or in an atmosphere substantially inert to the metal coating and metal substrate by irradiating the coated surface with electron beams or a plasma arc to form an alloy layer at the interface between the metal substrate and the anticorrosive metal coating. In an embodiment, subsequent to step (1) and prior to step (2) coating a solution of a thermally decomposable platinum-group metal compound on the surface of the anticorrosive metal coating, and heat-treating the resultant product at about 50 to about 300°C.
