GCr15/35CrMo摩擦副的塑性接触面积对滑动磨损的影响

Influence of Plastic Contact Area on Sliding Wear of GCr15/35CrMo Steel Tribo-pair

  • 摘要: 基于分形理论,计算了35CrMo钢试样经过压缩疲劳试验后变形区域以及和GCr15配副滑动磨损后的实际接触面积Ar、塑性接触面积Arp和塑性接触面积比率Arp/Ar,分析了塑性接触面积Arp和塑性接触面积比率Arp/Ar的变化量δArpδArp/Ar与磨损量的关系,采用扫描电子显微镜观察了35CrMo钢试样磨损表面的形貌.结果表明:35CrMo试块经过压缩疲劳以及和GCr15配副滑动磨损后,接触面材料的剥落引起了塑性接触面积Arp和塑性接触面积比率Arp/Ar的减少,塑性接触面积比率的变化量δArp/Ar可以描述磨损量的变化,当δArp/Ar<-0.5时,磨损量急剧增加.

     

    Abstract: The real contact area, plastic contact area and fraction of plastic contact area of 35CrMo specimen were calculated in two modes, i.e. deformation region after compression fatigue and worn surface in sliding against GCr15 using fractal theory. The relationships between wear and the plastic contact area, as well as the fraction of plastic contact area were analyzed. The worn morphology is observed using scanning electron microscopy. The results show that both the plastic contact area and the fraction of plastic contact area decreased as a result of delamination in contact area after sliding wear. The variation of the fraction of plastic contact area (δArp/Ar) can be used for variation of wear. Once the δArp/Ar was higher than the critical value, the wear increased sharply.
