Abstract
The present invention relates to tooling and methods for disposing, coating, building up, repairing, or otherwise modifying the surface of a metal substrate using frictional heating and compressive loading of a consumable metal material against the substrate. Embodiments of the invention include friction-based fabrication tooling comprising a non-consumable member with a throat and a consumable member disposed in the throat, wherein the throat is operably configured such that during rotation of the non-consumable member at a selected speed, the throat exerts normal forces on and rotates the consumable member at the selected speed; and comprising means for dispensing the consumable member through the throat and onto a substrate using frictional heating and compressive loading. Embodiments of the invention also include fabrication methods using the tools described herein.
