摘要/Abstract

摘要： 采用离子束辅助沉积技术在9Cr18轴承钢材料上制备掺杂Ag的WS₂固体润滑膜，并将该膜层在室内环境（温度为18～25℃，空气相对湿度为30%～50%）中保存8年。通过摩擦磨损试验机（MS-T3000）、场发射扫描电子显微镜、三维形貌仪及XPS检测保存前、后的WS₂-Ag固体润滑膜样品的摩擦磨损、表面形貌、三维形貌、成分及化学态。结果显示：贮存后的WS₂-Ag膜层内部氧含量的增加，膜层中Ag元素和少量W元素的氧化，以及S元素的损失，导致膜层摩擦磨损磨痕形貌出现了层状或者块状剥落；贮存后的WS₂-Ag复合固体润滑膜耐磨寿命有较贮存前的250 min缩短了103 min，仍然具有较好的固体润滑性能，其中Ag掺杂抑制了WS₂的潮解，提高了其抗氧化性能，大幅度延长了固体润滑膜的性能和寿命。

Abstract: The WS₂ solid lubricating films doped with Ag is prepared on 9Cr18 bearing steel by ion beam composite deposition technique. Then, the films is stored in an indoor environment (temperature 18 to 25℃, air relative humidity of 30% to 50%) for 8 years. The friction and wear, surface morphology, three-dimensional topography composition and chemical state of WS₂-Ag solid lubricant films are detected by friction and wear testing machine (MS-T3000), FESEM,surface morphology meter and XPS before and after storage. Compared with unstore WS₂-Ag solid lubrication film, The results show that the oxygen content increase, the oxidation Ag/W element, and the loss of S element are checked. The friction and wear morphology of the films has presented with lamellar or massive spalling. The wear resistance of WS₂-Ag composite lubricating films is shortened 103 minutes than before storage, the films still has a good solid lubrication performance, because the Ag doped WS₂, improve its deliquescence and antioxidant properties, which greatly prolongs life and performance of solid lubricating films.

Key words: anti deliquescence, long-term storage, solid lubricating films, WS₂-Ag
