ABSTRACT:
A metallic alloy part having a bonded coating that includes dispersed hard-material particles embedded in a metal matrix, composed of a eutectic solder whose alloy elements include at least the base metal of the metallic alloy part. The solder is formed by fusion bonding on the metallic alloy part, a precoating composed of sequential layers of the elemental components of the solder applied on the metal part or on the hard-material particles. The composition and disposition of the various layers are graduated such that the melting points of the elemental solder components increase towards the outermost layer.
