GRAIN BOUNDARY DIFFUSION PROCESS JIG, AND CONTAINER FOR GRAIN BOUNDARY DIFFUSION PROCESS JIG

摘要

grain boundary diffusion process to the present invention by heating the element R ^H was attached to the attachment (P) containing (Dy, Tb and Ho at least one of) the surface R ^L ₂ Fe ₁₄ B type magnet described in (S) is a challenge to provide a jig for welding difficult to grain boundary diffusion process. For the grain boundary diffusion treatment tool 10 is a front end (121) surface of the ceramic Jane protrusions 12 on the surface of the base 11. The plurality of plate-shaped, and is disposed above the front end 12 is such that the first plane. Projection 12 by placing the substrate (S) to the smaller contact area between the jig which deposits the grain boundary diffusion process attached to the surface of the substrate attachment (P) and a reaction using a hard ceramic by the substrate during the heating ( S) and the grain boundary diffusion is difficult to fuse the generation of the jig for processing (10). ;
