摘要

用电渣熔铸的方法制造了双金属复合材料锤头。双金属复合锤头头部材料采用高铬铸铁

锤柄采用碳素结构钢。对复合材料锤头组织性能进行了测试和分析。结果表明

锤头和锤柄之间有一个复合层区域

两种材料间发生了熔融和相互渗透

实现了两种金属的有效冶金结合。装机试验结果表明

双金属复合锤头使用寿命是高锰钢锤头的2倍左右。

Abstract

Bi-metal composite hammer head was produced by electroslag casting

in which high Cr cast iron was used for hammer head production and carbon structural steel was adopted in hammer handle. Microstructure and properties of the composite hammer head were analyzed. The results show that there exists a deeper metallurgical bonding zone between the hammer head and hammer handle

showing occurrence of the diffusion in two materials and realizing the desirable bonding. The experimental results verify that the service life of bi-metal composite hammer head is about 2 times higher than that of high Mn steel ones.
