摘　　要：采用高铬铸铁为镶块，钢筋做锤柄，应用镶铸方法生产复合锤头，实验结果表明：在较强烈冲击载荷的工况条件下，锤头的耐磨性约是高锰钢的2 倍；具有生产工艺简单、成本低、锤柄只有少量磨损，并且决不会折断等优点。High chromium cast iron is used for hammer inserts and re—bar done for hammer handle,which shows that the wear resistance is twice that of the manganese under the conditionsof severe shockIts advantages include easy manufacturing,low cost,less wearing andgood toughness
