Abstract
Methods for preparation of overlaid uniform amorphous alloy layers of prescribed compositions and thicknesses bonded tightly to the substrate metals are described. The methods involve previously coating the substrate metal surface with metal layers and irradiating with high energy density beams to cause a melting of the metal layer or layers including, if necessary, a portion of the substrate metal and thereby forming a uniform alloy metal of prescribed composition tightly bonded to the substrate metal surface, said irradiation being carried out during movement of the substrate or beams so as to control irradiation time and depth.
