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.

1. A friction-based fabrication tool comprising: a non-consumable member having a body and a throat;a consumable coating material;wherein the throat is shaped to exert a normal force on the consumable coating material disposed therein for imparting rotation to the coating material from the body when rotated at a speed sufficient for imposing frictional heating of the coating material against a substrate;wherein the throat contacts the entire length of the portion of the consumable coating material that is disposed in the throat;wherein the body is capable of dispensing and compressive loading of the coating material from the throat onto the substrate and is capable of rotating and translating the body relative to the substrate; andwherein the body comprises a surface for trapping coating material loaded on the substrate in a volume between the body and the substrate and for forming and shearing a surface of a coating on the substrate. 2. The tool of claim 1, wherein the throat of the non-consumable member is shaped with a non-circular cross-sectional shape. 3. The tool of claim 2, wherein the non-circular cross-sectional shape is a square, rectangle, ellipse, oval, triangle, non-circular polygon, star, daisy, key, or diamond. 4. The tool of claim 2, wherein the throat of the non-consumable member is shaped to exert normal forces on a solid, powder, or powder-filled tube type coating material disposed therein. 5. The tool of claim 1, wherein the throat of the non-consumable member is shaped to exert normal forces on a plurality of surfaces of a consumable coating material disposed therein. 6. The tool of claim 5, wherein the throat of the non-consumable member is shaped to exert normal forces on four or more surfaces of a consumable coating material disposed therein. 7. The tool of claim 1, wherein the consumable coating material and the throat have complementary shapes. 8. The tool of claim 7, wherein the consumable coating material and the throat have correspondingly shaped and sized cross sections along the entire length of the portion of the consumable coating material that is disposed in the throat. 9. The tool of claim 8, wherein the consumable coating material and the throat each have a square cross section. 10. The tool of claim 1, wherein the throat and the consumable coating material have a geometry configured to provide for engagement and disengagement of the tool and the consumable coating material. 11. The tool of claim 1, wherein the throat and the consumable coating material have a geometry configured to provide for interlocking of the tool and the consumable coating material. 12. A friction-based fabrication tool comprising: (a) a non-consumable member having a body and a throat;wherein the throat is shaped to exert a normal force on a consumable coating material along the entire length of the portion of the consumable coating material disposed therein for imparting rotation to the coating material from the body when rotated at a speed sufficient for imposing frictional heating of the coating material against a substrate;wherein the body is capable of dispensing and compressive loading of the coating material from the throat onto the substrate and is capable of rotating and translating the body relative to the substrate; andwherein the body comprises a surface for trapping coating material loaded on the substrate in a volume between the body and the substrate and for forming and shearing a surface of a coating on the substrate; and(b) a consumable coating material with a cross-section along the entire length of the consumable coating material that has the same shape as a cross-section of the throat. 13. The tool of claim 12, wherein during use the throat of the non-consumable member contacts the coating material along the entire length of the portion of the coating material that is disposed in the throat. 14. The tool of claim 12, wherein the throat of the non-consumable member is shaped with a non-circular cross-sectional shape. 15. The tool of claim 14, wherein the non-circular cross-sectional shape is a square, rectangle, ellipse, oval, triangle, non-circular polygon, star, daisy, key, or diamond.
