摘要

采用二极管泵浦声光调Q Nd:YAG激光器在45钢表面进行织构化处理,对填充不同质量分数聚酰亚胺(PI)的MoS₂复合固体润滑剂织构试样在销-盘线接触摩擦磨损试验机上进行了不同工况下的滚动摩擦性能实验。利用扫描电子显微镜观察和分析材料磨损形貌和元素分布。结果表明:填充黏结型MoS₂复合固体润滑剂织构表面的摩擦因数均随着载荷和转速的增大而减小,其中MoS₂+20%(质量分数)PI复合润滑剂具有最佳的减摩性能。在线接触滚动过程中,存在氧化磨损、磨粒磨损和黏着磨损。高速重载能促进转移膜在对偶面形成,显示出良好的减摩性能。

Abstract：

Q switched diode-pumped solid-state Nd: YAG laser was adopted to carry out texture processing on the surface of 45 steel. Rolling friction property test of textured samples filled with MoS₂ composite solid lubricant containing different mass fractions of PI was examined by a pin-plate line contact friction and wear tester under different working conditions. Wear morphologies and elements distribution were observed and analyzed by SEM. The results indicate that the friction coefficient of textured surface which is filled with bond-type MoS₂ solid lubricant decreases as the load and speed increase, and the composite lubricant containing MoS₂ plus 20%(mass fraction) PI has the best anti-friction property. The textured surfaces exist oxidation wear, abrasive wear and adhesive wear in the condition of line contact rolling. High speed and heavy load can promote transfer films forming on the counterpart face, and show good anti-friction performance.

Key words： laser texture composite solid lubricant line contact rolling friction
