Abstract:
1. A method for manufacturing a single body tool for performing friction stir welding, processing and mixing of high melting temperature materials, said method comprising the steps of: (1) providing a form for a single body friction stir welding tool comprising a shank, a shoulder, and a pin; (2) mixing a superabrasive material with a second phase material that is ceramic or metal based; (3) disposing the superabrasive material and second phase material mixture into the form wherein the superabrasive material and second phase material mixture will function as a coating on the single body friction stir welding tool; (4) disposing a substrate into the form, wherein the substrate will become the body of the single body friction stir welding tool; and (5) pressing the superabrasive material and second phase material mixture and the substrate in the form in a single pressing process to thereby create the single body friction stir welding tool that is capable of functionally friction stir welding, processing or mixing high melting temperature materials.
