摘要 通过传统重力浇注工艺,用高铬铸铁金属溶液铸渗ZrO2增韧Al2O3(ZTA)陶瓷颗粒蜂窝状预制体,从而获得高铬铸铁基蜂窝陶瓷复合材料。将复合材料在930 ℃、980 ℃、1 030 ℃、1 080 ℃温度下淬火,并分别在230 ℃、330 ℃、430 ℃、530 ℃时回火,研究了热处理条件对高铬铸铁基蜂窝陶瓷复合材料组织及三体磨料磨损性能的影响。研究结果表明:在相同回火温度条件下,随着淬火温度的升高,复合材料硬度升高,其耐磨性也随之升高;在相同淬火温度条件下,随着回火温度的升高,材料的硬度及耐磨性能也随之升高,两者达到一定温度后其硬度及耐磨性都下降, 材料耐磨性与材料的硬度变化趋势一致。最终得到复合材料的最佳热处理工艺为:1 030 ℃×2 h, 空冷+530 ℃×0.5 h。

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.
