Friction stir welding using a superabrasive tool
First Claim
1. A method for solid-state friction stirring of a surface of a high melting temperature material, said method comprising the steps of:
- (1) providing a friction stirring tool having a friction stirring surface;
(2) disposing a superabrasive material on the friction stirring surface; and
(3) friction stirring the surface of the high melting temperature material using a solid-state process wherein the high melting temperature material substantially avoids a liquid state.

Abstract
A probe for friction stir welding MMCs, ferrous alloys, non-ferrous alloys, and superalloys, as well as non-ferrous alloys, the probe including a shank, a shoulder, and a pin disposed through the shoulder and into the shank, wherein the pin and the shoulder at least include a coating comprised of a superabrasive material, the pin and shoulder being designed to reduce stress risers, disposing a collar around a portion of the shoulder and the shank to thereby prevent movement of the shoulder relative to the shank, and incorporating thermal management by providing a thermal flow barrier between the shoulder and the shank, and between the collar and the tool.
