Abstract:
1. A process and apparatus for energy beam assisted solid-state metallurgical bonding of a wire, having two or more flat surfaces, to a substrate, for the purpose of substrate coating, 3-Dimensional component buildup, restoration and component surface improvement, and comprising the steps of: applying of a continuously fed wire to a substrate such that the bottom of the wire flat surfaces are tangential to the substrate such that the contact of the wire with the substrate constitute substantially a surface; an energy beam is simultaneously applied to the wire, with a magnitude controlled to be sufficient to produce a sudden compressive shock wave and heat at the surface of the wire to propagate through the wire and the top surface of the substrate; whilst some material particles of the wire are carried with the shock wave and are penetrating into the substrate, producing a strong metallurgical bond without substantial liquefaction of the substrate.
