摘　　要：采用3种谐波减速器用刚轮材料——2Cr13不锈钢、40Cr中碳合金钢、45钢,通过对其显微组织、硬度、三维及二维形貌的显微磨损、摩擦因数的分析,探究不同材料耐磨性能的差异。结果表明,2Cr13、40Cr的显微组织为回火索氏体,45钢的显微组织为铁素体与珠光体。2Cr13、40Cr硬度相近且远大于45钢。2Cr13磨损形貌为黏着与剥落,磨损机制为黏着磨损;40Cr、45钢磨损形貌为犁沟与剥落、犁沟与黏着,磨损机制为磨粒磨损。3种材料的摩擦因数相差可忽略不计。2Cr13、40Cr、45钢截面的磨损面积分别为5008、1645、6535μm2。硬度相近下,40Cr表现出比2Cr13更优异的耐磨性能。45钢与摩擦副材料的硬度值相差最大,耐磨性能最差。Three kinds of circular spline materials are studied for harmonic reducers,stainless steel 2Cr13,medium carbon alloy steel 40Cr,carbon 45 steel.Through the analysis of microstructure,hardness,three-dimensional and two-dimensional morphology in microwear and friction coefficient,the differences in wear resistance of different materials are attained.The results show that the microstructures of 2Cr13 and 40Cr are tempered sorbite,and the microstructure of 45 steel is ferrite and pearlite.The hardness of the 2Cr13 and 40Cr is similar and much larger than that of the 45 steel.The morphology of 2Cr13 is adhesion and spalling,and the wear mechanism is adhesion wear.The morphology of 40Cr and 45 steel is furrow and spalling,furrow and adhesion,and the wear mechanisms are abrasive wear.The friction coefficients'differences of the three materials are negligible,and the area of wear of 2Cr13,40Cr and 45 steel are 5008µm2,1645µm2 and 6535µm2.40Cr exhibits better wear resistance than 2Cr13 with similar hardness.The hardness difference between 45 steel and the friction pair material is the largest,and the wear resistance of the 45 steel is the worst.
