摘　　要：研究了Q235钢溶液中微等离子体渗硼处理。用金相显微镜观察了渗硼层的显微组织,用SEM观察了渗硼层的表面形貌,借助显微硬度计测试了渗层的硬度,用盘销式摩擦磨损试验机测试了渗层的润滑摩擦性能。结果表明:溶液中微等离子体渗硼处理的渗硼层硬度约为基体硬度的5倍,润滑摩擦性能提高。The Q23S steel surface layer was made by micro-boriding in the aqueous solution. The metallographic structure, surface morphology, micro-hardness and lubrication friction of the coating were evaluated by OM, SEM, micro-hardness tester and pin-on-disk friction tester, respectively. The results show that the hardness of the surface layer is 5 times that of the matrix and the surface strengthening texture improves the lubrication friction greatly.
