本工作通过摩擦过程中聚醚醚酮（ＰＥＥＫ）结构（包括材料与磨屑结构）的变化研究了ＰＥＥＫ的摩擦磨损机理。结果表明，低负载下，材料的摩擦表面不熔融，但表层的凝聚态结构发生了变化，摩擦状态不变，磨损是由于摩擦对偶的连续作用下产生疲劳而脱落。高负载下，材料表面熔融并发生氧化交联，摩擦状态改变，材料外形结构与内层凝集态结构发生变化，磨损是熔融了的表面层粘附于对偶上经进一步的交联反应后，受剪切力作用而脱落。材料在摩擦磨损过程中的表面状态决定了其摩擦磨损机理，并导致了材料摩擦磨损行为对负载的特殊依赖性。
In this work, the friction and wear mechanism of PEEK was studied by the change of PEEK structure (including the structure of material and wear debris) during the friction process. The results show that under low load, the friction surface of the material does not melt, but the condensed state structure of the surface layer changes, the friction state remains unchanged, and the wear is due to fatigue and falling off due to the continuous action of the friction pair. Under high load, the surface of the material is melted and oxidized and cross-linked, the frictional state changes, the structure of the material changes with the agglomeration structure of the inner layer, the worn surface layer is melted and adhered to the couple. Upon further crosslinking reaction, Shear force and fall off. The surface state of the material during the friction and wear process determines its friction and wear mechanism and leads to the special dependence of the friction and wear behavior of the material on the load.
