Abstract:
1. A friction surfacing apparatus for depositing one or more metals, metal alloys, or other materials, the friction surfacing apparatus comprising: a pin tool holder; a non-consumable shoulder having an inside diameter, an outside diameter and terminates at an end wall, the inside diameter includes an angled side wall that extends radially inward from the end wall to form a substantially frustoconical opening at one end; and a consumable pin tool coupled to the pin tool holder, the pin tool at least partially protruding from the end wall of the shoulder, wherein the end wall of the shoulder is maintained at a predetermined distance from a surface of a workpiece such that the shoulder forges a layer of consumable pin tool material onto the surface of the workpiece during a friction surfacing operation, thereby creating a mechanical and chemical bond between the consumable pin tool material and the surface of the workpiece.
