A systematic study comparing the wear behaviour of composites with nylon matrix (PA66, PA46, PA12) and different nanoadditives and reinforcing additives (graphite, graphene, MoS and ZrO) has been carried out in order to achieve a proper self-lubricant material for bearing cages. The wear characterisation was done using pin-on-disc tests, SEM and EDX analysis. The results show that better outcomes are obtained for composites based on PA12. The addition of ZrO offers negative values of wear due to the metallic particle transference from the counterface to the polymeric pin.
为了获得一种适用于轴承保持架的自润滑材料,已经开展了一项系统研究,比较了具有尼龙基体(PA66、PA46、PA12)以及不同纳米添加剂和增强添加剂(石墨、石墨烯、MoS和ZrO)的复合材料的磨损行为。磨损特性通过销盘试验、扫描电子显微镜(SEM)和能谱分析(EDX)进行表征。结果表明,基于PA12的复合材料取得了更好的结果。由于金属颗粒从配对面转移到聚合物销上,添加ZrO会导致磨损值为负。
