Abstract:
1. A method of producing a metal-matrix composite coating on a surface of a substrate comprising: a) melting a portion of said surface of said substrate with a heat source forming a melt pool; b) feeding a reinforced metal matrix precursor into a melt zone so that molten precursor drops enter said melt pool; c) allowing said molten precursor and melted substrate to mix, react and mix and react in said melt pool; d) solidifying said pool forming a compound that coats said portion of said surface of said substrate; and e) repeatedly redirecting said heat source to another portion of said surface and repeating steps a-d until a desired portion of the substrate surface is coated, and wherein said heat source comprises a distributed source and said precursor comprises a contoured sheet precursor, and said contoured sheet precursor comprises a mesh sheet.
