The role of reduced iron powder in diamond matrix

After reduced iron powder is added into diamond tool, the alloying degree of diamond tool tire is improved, the microstructure of sintered body is uniform, the control of diamond tool tire is improved, the sintering heat holding time is short, the loss of metal with low melting point is small, the structure is compact and the self-sharpening is good. It can not only prolong the wear resistance of diamond tools, but also improve the tool sharpness, so as to improve the comprehensive performance of diamond tools.
