摘　　要：介绍了高铬铸铁-碳钢复合锤头的镶铸工艺,检测其力学性能、耐磨性及不同温度下界面结合处的金相组织等。结果表明,复合锤头具有较高的力学性能;在相同工况条件下,用镶铸法生产的复合锤头,其寿命是高锰钢的2倍多,且生产工艺简单,成本低。This article describes the inlay casting technology of the composite hammer with high-chromium iron and carbon steel and detects its mechanical properties, abrasion resistance, interface microstruetures at different temperatures, etc. The results show that this composite hammer has higher mechanical properties. Under the same working conditions, its service life is 2 times more than that made of high manganese steel and it has the simple production process and the low cost.
