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30 μm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。

Abstract:
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 coatings thickness were analyzed with Energy Dispersive Spectroscopy X?ray analysis system (EDS) and Scanning Electronic Microscope (SEM). The bonding strength of the coatings with the substrate was tested through cooling quenching test. The results indicated that self?repairing coatings with the thickness of 30 μm were formed on the wearing steel surface after using the lubricant, and the coatings were well combined with the substrates. The test also proved that the repaired steel surface possessed excellent friction?reducing and anti?wear capability.
Key words:  soft metal additives  self?repairing  steel vs. steel tribo?pair  tribological property  bonding strength
