摘　　要：采用对比试验的方法探讨了不同Cr/C的比值对含4%Ni高铬耐磨耐蚀铸铁硬度、耐磨性及冲击韧性的影响规律。结果表明:无论固定C还是固定Cr,改变Cr/C的比值对4%Ni高铬耐磨耐蚀铸铁性能都有显著的影响,尤其当含C量较低时,Cr的变化对材料性能的影响更明显。通过调整不同的Cr/C,可以获得不同的硬度、耐磨性和冲击韧性组合的材料。In this article, the effect law of hardness, resistance to wear and impact toughness of high Cr wear resistant and corrosion resistant cast iron with 4%Ni is studied by contrast experiments, The experimental results show that whether Cis constant or Cr is constant, the change of Cr/C has obvious effects on the property of high Cr wear resistant and corrosion resistant cast iron with 4%Ni, especially when the content of Cis low, the property of high Cr wear resistant and corrosion resistant cast iron with 4%Ni,especially when the content of Cis low, the effect of the change of Cr is more obvious. We can gain different materials with different hardness, resistance to wear and impact toughness by changing Cr/C.
