摘要
用模压方法制备了Ekonol G MoS2 PEEK复合材料,通过摩擦磨损实验方法对其在不同转速下摩擦学性能进行了研究,并用SEM对磨损表面进行了观察和分析,在此基础上探讨了复合材料的磨损机理.结果表明:PEEK复合材料摩擦系数的大小与转速的大小有关;在300rpm以下,随着转速的增大,复合材料的磨损呈先增加后减小趋势,其磨损机理发生了由粘着磨损向疲劳磨损的转变.转速大于300rpm时,复合材料的摩擦系数再次增大,磨损加剧.图8,参11.
Ekonol/G/MoS_2/PEEK composite was prepared by the compressing model method. The tribology behavior has been investigated by friction and wear experiment. The wear surface of the composite has been studied by the SEM technique, and on the base of it, the wear mechanism has been analyzed. Results show that the friction coefficient is related to the rotate speed. Below 300 rpm, with the increase of the rotate speed, the wear loss is increased first, and then decreased. With the increase of the rotate speed, the wear mechanism has been changed from the adhesion wear to the fatigue wear. When the rotate speed is over 300 rpm, the friction coefficient of the composite is rise again, and the wear is also severe. 8figs.,11refs.
