Abstract: The high chromium cast iron metal infiltrated the honeycomb preform of ZrO2 toughened Al2O3(ZTA) ceramic particles by the traditional gravity casting process and obtained the honeycomb ceramic particles reinforced high chromium cast iron matrix composite.The effect of heat treatment on the organization and properties of the three body abrasive wear about the composite was studied at the quenching temperature of 930 ℃, 980 ℃, 1 030 ℃, 1 080 ℃ and at the tempering temperature of 230 ℃, 330 ℃, 430 ℃, 530 ℃, respectively. The results show that at the same tempering temperature, the hardness of the composite increased and the wear resistance also increased with the increase of quenching temperature. While at the same quenching temperature, the hardness of the composite increased and the wear resistance increased with the increase of tempering temperature. The hardness and wear resistance were declined when the quenching temperature and the tempering temperature reached a certain value. The wear resistance of the composite changed consistently with the hardness. Eventually, the optimum heat treatment process for the composite was quenching at 1 030 ℃ 2 h, air cooling+tempering at 530 ℃×0.5 h.
