摘要
针对目前润滑自修复技术生成的修复层厚度较薄,难以修复较严重磨损表面的不足,研制了含铟、锡和锌三种软金属添加剂的新型磨损自修复润滑剂。在摩擦磨损试验机上,考察了使用该润滑剂的钢?钢面接触摩擦副的磨损自修复行为及其摩擦学性能。用X射线能谱(EDS)和扫描电镜(SEM)分析了修复表面的主要化学元素和自修复涂层的厚度。用淬冷试验测试了涂层与基体的结合强度。结果表明,研制的铟锡锌润滑脂能在钢表面摩擦形成约30μm厚度的自修复涂层,涂层与基体结合性能良好,修复后的钢表面有良好的减摩抗磨性能。
At present,the repairing coatings formed through lubricating self-repairing technique are too thin to repair those seriously worn surfaces.This paper developed a new type of wearing self-repairing lubricant that contained three kinds of soft metal additives-In,Sn and Zn.The behavior of wearing self-repairing and its tribological performance on steel vs.steel plane contact tribo-pair added with the lubricant were studied on a friction and wear tester.The main chemical elements of self-repair surface and coat...
