PCT No. PCT/CH86/00026 Sec. 371 Date Nov. 3, 1986 Sec. 102(e) Date Nov. 3, 1986 PCT Filed Feb. 25, 1986 PCT Pub. No. WO86/05213 PCT Pub. Date Sep. 12, 1986.The metal substrate (4) is covered with a coating (6) consisting of another metal or alloy having a thickness of 4 to 50 mu m, by deposition of molten metal or alloy (5) through a nozzle (2), this melting point [sic] being lower than that of the substrate metal. This coating comprises, at the interface with the substrate, a layer of intermetallic compound with a thickness of between 0.5 and 4 mu m not exceeding 40% of the total thickness, the remainder consisting of the initial metal or alloy used for the coating, in a proportion of between 97% and 99.5% by weight.
