针对目前有较好应用前景的新型水润滑轴承材料,利用环-块摩擦磨损试验机试验研究了赛龙、飞龙、超高分子量聚乙烯在淡水介质和人工海水介质中的滑动摩擦磨损性能,结合扫描电子显微、白光共焦三维形貌仪等检测手段,探讨材料的摩擦磨损机理。结果显示:在两种试验介质中,赛龙/GCr15摩擦副的摩擦系数最高,超高分子量聚乙烯/GCr15摩擦副的摩擦系数最小;超高分子量聚乙烯的磨损体积最小,飞龙最大,赛龙居中。磨损机制主要为磨粒磨损。在海水介质中,飞龙材料表面粘附有大量结晶盐颗粒,在摩擦磨损过程中有增加磨损的作用。
Aiming at the new water-lubricated bearing materials with good application prospects, the sliding friction and wear properties of Cyhalon, dragon and ultra-high molecular weight polyethylene in freshwater medium and artificial seawater medium were studied by ring-block friction and wear testing machine. Scanning electron microscopy, white light confocal three-dimensional topography and other testing methods to explore the friction and wear mechanism of the material. The results show that the coefficient of friction of Seron / GCr15 friction pair is the highest, and the friction coefficient of UHMWPE / GCr15 friction pair is the smallest among the two test media. The wear volume of UHMWPE is the smallest, Center. Wear mechanism is mainly abrasive wear. In the seawater medium, a large number of crystal salt particles adhere to the surface of the dragon’s material, which has the effect of increasing the wear during the friction and wear.
