目的：改善AISI316不锈钢的摩擦磨损性能。方法采用双辉等离子合金化技术,以块状FeB化合物作为源极材料,在AISI316不锈钢表面制备含硼改性层,对渗层组织、成分、相结构和显微硬度进行分析,并研究改性层在干摩擦条件下的摩擦磨损性能。结果经渗硼处理后,AISI316不锈钢表面形成了一层连续、致密、均匀的改性层,主要由Mo2B和FeB相组成。改性层具有较高的硬度(964HV0.1),较基体硬度提高了约3倍,且耐磨性较基体有明显提高。结论通过在AISI316不锈钢表面制备渗硼改性层,可明显提高基体材料的硬度和摩擦磨损性能。

Objective To improve the tribological performance of AISI316 stainless steel. Methods A boron modified layer was successfully prepared on the surface of AISI316 stainless steel using double glow plasma alloying technology with FeB compound solid as the precursor. The microstructure, composition, phase structure and micro-hardness of the boronized layer were character-ized, and the friction and wear behavior of the modified layer was investigated under dry sliding friction conditions. Results The study showed that, a dense, uniform and continuous modified layer, mainly composed of Mo2 B and FeB phase, was formed on the surface of AISI316 stainless steel after boronizing treatment. The modified layer had higher hardness (964HV0. 1) , which was 3 times higher than that of the substrate, and the wear resistance was significantly improved compared with the substrate. Conclusion Preparation of boron modified layer on the surface of AISI316 stainless steel could significantly improve the hardness and the tribo-logical performance of the substrate material.
