利用原位反应方法在PPS涂料中掺杂CuO,通过浸涂制备了CuO/PPS复合涂层.利用热重分析仪测试了涂层的热性能,选用销盘式磨损实验机测试了涂层的摩擦学性能,采用SEM观察分析了磨损表面,并在此基础上探讨了磨损机理.研究结果表明,涂层表面平整光洁,复合涂层热稳定性较PPS树脂有所提高,热分解温度提高;CuO的加入使PPS复合涂层摩擦学性能得到明显的改善.同时发现,在相同条件下,涂层的磨损机理与CuO添加量密切相关.

The copper oxide/polyphenylene sulfide composite coatings are prepared by in-situ reactive method,with copper oxide mixed in polyphenylene sulfide coatings.The thermal property of the composites coating is tested by Thermogravimetric and Differential Thermal analyzer.The tribological behaviour is investigated on pin-on-disc sliding friction and wear tester.The worn surfaces of the composite coatings are observed and analyzed by the SEM technique,and then the worn mechanism is discussed.Results show that the coating surface is flat and glossy.The thermostability of the composite coatings is improved,the decomposition temperature of which are higher than pure polyphenylene sulfide resin.The tribological properties are obviously improved with the addition of copper oxide.The mechanism of coatings is closely related to the contents of copper oxide under the same experimental conditions.
