高锰钢镶铸硬质合金锤头的研制

A Study of High Manganese Steel Hammers with Inserted Hard Alloy

探讨了高锰钢镶铸硬质合金锤头的制造方法 ;介绍了硬质合金基体成分、镶铸工艺和热处理工艺 ,作了试样界面观察和硬度检测 ;试验表明 ,2种材料界面呈冶金结合 ;该锤头的使用寿命是高锰钢锤头的 3倍。

The process of high manganese steel hammers with inserted hard alloy is discussed.The interface is found to be a metallurgical bond. Field test showed that the service life of the new hammers was three times as long as that of the traditional high manganese steel hammers.
