采用添加稀土化合物及优化工艺参数的方法解决了4Cr13不锈钢渗硼问题.通过正交试验法获得4Cr13钢渗硼工艺为:温度920 ℃,时间8 h,最佳稀土加入量为0.5%(质量分数).借助于金相显微镜、X射线衍射仪及显微硬度计,观察和分析了加稀土前后渗层的组织、表面和次表面的相结构以及渗层的显微硬度分布.结果表明:加稀土元素后,渗层厚度提高,硼化物的组织形态及致密度明显改善,表面获得以Fe2B、(Fe,Cr)2B为主的组织,渗层脆性降低.

The boron infiltration problem of 4Cr13 stainless steel was solved by adding rare earth compounds and optimizing the process parameters. The boronizing process of 4Cr13 steel obtained by orthogonal test method was: temperature 920 °C, time 8 h, and the optimal rare earth addition amount was 0.5% (mass fraction). The results showed that after the addition of rare earth elements, the thickness of the permeable layer increased, the micromorphology and density of boride were significantly improved, the predominant tissues of Fe2B and (Fe, Cr)2B were obtained on the surface, and the brittleness of the permeable layer decreased.
