摘    要：利用双层辉光离子渗金属技术可在工业纯铁表面形成铁、钨、钼、钴时效合金。研究了形成这种合金的表面冶金工艺和渗层组织状态、渗层成分分布以及渗金属工艺参数改变对渗层厚度及渗层成分分布的影响。结果表明，表层W，Mo，Co含量可达到高Co时效合金W11Mo7Co23的水平，Co含量为1 8%～30%，W含量为7%～17%，Mo含量为5%～9%。

Abstract: Surface age-hardening alloy of Fe-W-Mo-Co may be formed on surface of industrial pure iron by use of double glow plasma surface alloying technique. Surface metallurgical technology of the surface alloy, structure and distribution of composition in alloying layer, and influence on change of technological parameter of thickness of alloying layer and distribution of composition were investigated. The results showed that the contents of W, Mo, Co in surface reach the content level of age-hardening alloy of W11Mo7Co23, contents of Co ranges from 18% to 30%, that of W ranges from 7% to 17% and that of Mo ranges from 5% to 9%.
