Wear resistant iron powder article |
摘要 |
A wear resistant iron alloy article is preferably formed by compacting and sintering a predominantly iron powder mixture containing additions of carbon, copper and nickel boride. The product microstructure comprises hard borocementite particles dispersed in a martensite or pearlite matrix. The particles have a cross-sectional dimension greater than 1 micron and are present in an amount preferably between 10 and 30 volume percent to improve wear resistance.
