用反应铸造技术，在铸钢件表面合成了厚度为４．２ｍｍ的Ｆｅ－ＴｉＣ表面复合材料。该表面复合材料中同时含有铬的碳化物和片状石墨，ＴｉＣ的颗粒大小为１～３μｍ，在亚表面层中，ＴｉＣ的体积分数高达３８％，由表及里，Ｆｅ－ＴｉＣ表面复合材料的组织和成分皆呈梯度分布，逐渐过渡到母体合金。在重载干滑动磨损条件下它显示了非常好的耐磨性能 Using reaction casting technology, a thickness of 4.2mm Fe-TiC surface composite was synthesized on the surface of cast steel. The surface composite material contains both chromium carbide and flake graphite. The particle size of TiC is 1-3 μm. In the subsurface layer, the volume fraction of TiC is as high as 38%. The surface composites The organization and composition are gradient distribution, the gradual transition to the parent alloy. It shows very good wear resistance under heavy dry sliding wear conditions
