中文摘要：在SRV Ⅳ微动磨损试验机上考察了氮化激光复合处理和正火 + 高温回火处理对18Cr2Ni4WA钢抗微动磨损性能的影响。结果表明：在试验条件下，渗氮激光复合处理试样的维氏硬度约为780 HV，具有较好的抗微动磨损性能。磨损机理主要为粘着磨损和磨粒磨损。
英文摘要：Fretting wear resistance of 18Cr2Ni4WA steel with nitriding and laser quenching was studied on a SRVⅣoscillating friction and wear tester. The results show that the hardness of sample after nitriding and laser quenching is about 780 HV, and the sample has excellent fretting wear resistance. The main fretting wear mechanism is abrasive wear and adhesion wear.
