SINTERED BODY AND METHOD FOR PRODUCING SAME; SLIDING MEMBER, FILM-FORMING MATERIAL AND DIE FOR HOT EXTRUSION MOLDING EACH USING SUCH SINTERED BODY; AND HOT EXTRUSION MOLDING APPARATUS AND HOT EXTRUSION MOLDING METHOD EACH USING SUCH DIE FOR HOT EXTRUSION MOLDING

摘要

By using a sintered body composed of 58-92.5% by mass of TiCN, 0.01-1% by mass of Ti, 0.01-2% by mass of TiC, 0.01-2% by mass of TiN and the balance of TaC, Ni and Cr, there can be obtained a sliding member, film-forming material and die for hot extrusion molding which exhibit high strength, high hardness, high toughness and high sliding properties in an environment of about 400-600˚C, and a hot extrusion molding apparatus using such a die for hot extrusion molding.
