Steel-bonded carbides are P/M materials that are intermediate in wear resistance between tool steels and cemented carbides based on WC-Co, They consist of 25 to 45 vol% TiC homogeneously dispersed in a steelmatrix.
TiC Cermets with Various Steel Binder Compositions. The wetting and solubility characteristics of TiC make it compatible with a great many alloy steels for formulating steel-bonded carbide cermets. From the many possible combinations, a few significant ones have been developed into actual cermet grades.
TiC particles have high hardness, high melting point, low density, appropriate wettability, and also chemical stability in iron,TiC particles have high hardness, high melting point, low density, appropriate wettability, and also chemical stability in iron. Moreover, the Fe-TiC metal matrix composites (MMC) show attractive functional properties such as high wear resistance ,high tensile strength, and proper ductility.
