ABSTRACT:
A metal coating is deposited on a metal substrate by means of a method which consists in sand-blasting the metal substrate, in heating the substrate to a temperature between 100.degree. and 650.degree. C, then in spraying a powder of nickel or cobalt alloy having a high value of hardness and containing reducing agents as well as agents for reducing the melting point, the spraying operation being performed at a distance of 50 to 200 mm from the nozzle of a spray-gun and at a velocity within the range of 100 to 250 meters per second.
