摘　　要：目的介绍自主研发的氟聚合物耐磨自润滑涂层(简称为协合涂层)的基本性能、测试评价结果、工程应用效果及方向。方法采用TOKYO SEIMITSU Surfcom测量仪、SEM、电子探针线扫描分析、显微硬度仪、球盘式磨损试验仪、MM摩擦试验仪、Table摩擦磨损试验仪、CI4000氙灯老化测试仪及FY-10E盐雾试验箱等,对涂层的性能进行了表征,并且通过应用实例分析介绍了该涂层的主要应用情况。结果涂层厚度可控制在20~60μm,铝合金涂层硬度为400~600HV,钢铁材料涂层硬度为700~950HV,涂层摩擦系数小于0.15,磨损量小于50 mg/10 000 r,耐中性盐雾试验达336 h以上,抗光老化试验800 h,在165℃仍具有高温阻粘性能。涂层的综合防护性能突出,可满足耐磨、自润滑、耐腐蚀、耐温、阻粘等单一或综合功能性防护需求。结论氟聚合物耐磨自润滑涂层兼有阳极氧化膜或电镀层与控制渗入的低摩擦聚合物或润滑剂的优点,在铝合金和钢铁材料上的规模化应用表明,该涂层的性能和工艺技术状态稳定,具有广泛的工程应用价值。The work aims to introduce basic properties, test and evaluation results as well as engineering application effect and direction of self-developed anti-abrasive self-lubricating fluoropolymer coating（referred to as synergistic coating）. Properties of the coating were characterized with TOKYO SEIMITSU Surfcom gauge, SEM, electron probe line scanning analysis, microhardness tester, ball-disc wear tester, MM friction tester, Table friction-wear tester, CI4000 xenon lamp aging tester, FY-10 E salt spray test chamber etc. Main applications of the synergistic coating were introduced by analyzing application examples. Coating thickness should be controlled between 20~60 μm, coating hardness on aluminum alloys should be 400~600 HV, coating hardness on steel 700~950 HV, coating friction coefficient below 0.15, wear loss below 50 mg/10 000 r, resistance to 5% neutral salt spray test over 336 h, and anti-ageing resistance 800 h. The coating still maintained prominent high temperature abhesion at 165 ℃. The coating exhibited outstanding comprehensive protective performance, hence it can meet requirements of single or overall functional protection including wear resistance, self-lubrication, corrosion resistance, temperature resistance and abhesion. The anti-abrasive self-lubricating fluoropolymer coating has integrated advantages of anodic oxide film or electroplated layer, and low friction fluoropolymer or lubricant featuring penetration control. Its large-scale application to steel and aluminum alloy materials shows that properties and technological state of the coating are stable, hence the coating is of extensive engineering application value.
