将碳纤维增强聚四氟乙烯(PTFE)复合材料分别与4032铝合金和阳极氧化4032铝合金组成摩擦副,在干摩擦和油润滑条件下进行摩擦磨损试验,对摩擦因数、磨痕宽度及磨损形貌进行了研究.结果表明:在干摩擦条件下,复合材料与铝合金配副时,产生了严重的磨粒磨损,复合材料的磨痕宽度较大;复合材料与阳极氧化铝合金配副时,磨损机理主要为黏着磨损,并伴随着轻微的磨粒磨损,复合材料的耐磨性能有所改善;在油润滑条件下,随着碳纤维含量增加,复合材料在与铝合金和阳极氧化铝合金配副时的磨痕宽度均下降,磨损过程未出现磨粒磨损.
Friction pairs were composed of carbon fiber reinforced polytetrafluoroethylene (PTFE) composites and 4032 aluminum alloy or anodized 4032 aluminum alloy.Coefficient of friction, scar width and wear morphology were studied by friction and wear test under the conditions of dry friction and oil lubrication.The results show that, under dry friction condition, the serious abrasive wear emerged during the wear process of composites against aluminum alloy, and the scar width is larger.The adhesive wear acted the major role during the wear process of composites against anodized aluminum alloy, and the wear process accompanied by slight abrasive wear.Under oil lubrication condition, with the increase of carbon fiber content, the scar widths of the composite against aluminum alloy or anodized aluminum alloy were decreased, the abrasive wear was not emerged during the wear process.
