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.

A method for manufacturing a mechanical seal used in fluid applications, wherein the mechanical seal is comprised of a sintered (cemented) tungsten carbide ring that is turned on a lathe at a negative top rake angle instead of formed by grinding. The cemented tungsten carbide ring is initially prepared by rounding corners of the top surface to form a radii. The resulting mechanical seal yields significantly less surface damage, can be formed using faster cutting speeds and feeds than when grinding, enables formation of a greater range of complex geometries for the mechanical seals, and requires fewer passes than grinding. The compact is also formed at a significantly reduced cost as compared to grinding.
