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5 008、1 645、6 535 μm

。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 5 008 μm

1 645 μm

and 6 535 μm

. 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.
