摘　　要：合理的配副能够提高轮胎活络模具摩擦副的服役寿命,但目前缺乏对轮胎活络模具实际摩擦工况下配副的研究,针对此现状开展了研究,为合理选择轮胎活络模具的摩擦副提供指导。为模拟轮胎活络模具实际摩擦工况,自主研发了试验设备,分别采用激光淬火试块、Ni⁃P合金试块、QPQ(氮碳氧复合处理技术)试块与铜⁃石墨自润滑材料配副,对比了3组摩擦副的摩擦系数、磨损量、磨损后表面以及磨屑的形貌和成分,阐明了摩擦磨损的机理。结果表明:与铜⁃石墨自润滑材料配副,激光淬火试块和QPQ试块的摩擦系数曲线平缓稳定,而Ni⁃P合金试块的摩擦系数曲线波动范围较大,平均摩擦系数由小到大依次为激光淬火试块<Ni⁃P合金试块<QPQ试块;在摩擦过程中,激光淬火试块不断以磨粒磨损的形式损耗,QPQ试块基本无磨损,表面仅受轻微的磨粒磨损,而Ni⁃P合金试块表面无损伤;与激光淬火试块配副,铜⁃石墨自润滑材料以磨粒磨损、黏着磨损、疲劳磨损的形式损伤,在Ni⁃P合金/铜⁃石墨摩擦副中,铜⁃石墨自润滑材料主要以黏着磨损的形式损耗,而与QPQ试块配副,铜⁃石墨自润滑材料则以磨粒磨损的形式不断磨损,磨损量从小到大排列顺序依次为QPQ试块<激光淬火试块<Ni⁃P合金试块。综合摩擦副的磨损情况,与铜⁃石墨自润滑材料配副,QPQ试块最为适用,服役寿命最长。Reasonable matching can improve the service life of the friction pair of tire active molds,but there is a lack of research on the matc⁃hing of tire active molds under actual friction conditions.In view of this situation,a study was conducted to provide guidance for the rational se⁃lection of friction pairs for tire active molds.To simulate the actual friction conditions of tire active molds,test equipment was independently de⁃veloped.Laser quenching test blocks,Ni⁃P alloy test blocks and QPQ(nitrogen⁃carbon⁃oxygen composite treatment technology)test blocks were respectively employed to be paired with the copper⁃graphite self⁃lubricating material.Additionally,the friction coefficient,wear loss,morphology and composition of the worn surface and debris of the three groups of friction pairs were compared,and the mechanism of friction and wear was explained.Results showed that when paired with copper⁃graphite self⁃lubricating material,the friction coefficient curves of laser quenching test block and QPQ test block were gentle and stable,while the friction coefficient curve of Ni⁃P alloy test block had a large fluctua⁃tion range.Moreover,the order of the average friction coefficient from small to large was laser quenching test block<Ni⁃P alloy test block<65 QPQ test block.During the friction process,the laser quenching test blocks were constantly worn out in the form of abrasive wear,the QPQ test blocks were basically not worn out,and the surface was only slightly worn out by abrasive wear,while the Ni⁃P alloy test blocks had no surface damage.When paired with laser quenching test blocks,the copper⁃graphite self⁃lubricating material was damaged in the form of abrasive wear,adhesive wear and fatigue wear.In the Ni⁃P alloy/copper⁃graphite friction pair,the copper⁃graphite self⁃lubricating material was mainly dam⁃aged in the form of adhesive wear.In contrast,the copper⁃graphite self⁃lubricating material was continuously worn in the form of abrasive wear when paired with QPQ te
