PRODUCTION OF INJECTION MOLDING AND SINTERING MATERIAL OF METAL POWDER AND INJECTION MOLDED AND SINTERED PRODUCT OF METAL POWDER

摘要

PROBLEM TO BE SOLVED: To improve the wear resistance of an injection molding and sintering material of ferrous metal powder. ;SOLUTION: Hard grains 5 in the amount of 3.0-6.0wt.% are dispersed in a ferrous base metal powder for injection molding and sintering material of metal powder. The ferrous base metal powder 6 is composed of one or ∞2 kinds selected from stainless steel, pure iron, nickel-containing iron, cobalt- containing iron, and chromium-molybdenum steel. Further, the hard grains 5 are selected from ceramic materials, such as titanium nitride(TiN) and chromium nitride(CrN), or from intermetallic compounds.;COPYRIGHT: (C)1997,JPO
