Abstract In this high energy padding method for forming a padding layer of padding metallic material on the surface of a base piece of cast iron material, a coating of metallic material containing copper is overlaid on the surface of the base piece of cast iron material, and a layer of the metallic padding material is deposited on the surface of the base piece of cast iron material over the copper containing coating metallic material layer thereon while using a relatively high energy density energy source, such as a laser, as a source of heat. The thickness of the overlaid copper containing coating metallic material layer may be between about 30 microns and about 500 microns. The copper content of the metallic material containing copper may be between about 80% and about 100%. And the overlaid copper containing coating metallic layer may be likewise formed by depositing of a metallic material containing copper on the surface of the piece of cast iron material while using a relatively high energy density energy source, such as a laser, as a source of heat.
A high energy padding method for forming a padding layer of padding metallic material on the surface of a base piece of cast iron material, comprising the steps of: (a) overlaying a coating of metallic material containing copper on said surfce of said base piece of cast iron material; and: (b) depositing a layer of said metallic padding material on said surface of said base piece of cast iron material over said copper containing coating metallic material layer thereon while using a relatively high energy density energy source as a source of heat.
