摘要
在MS-800型改造四球式试验机上,对钢-铜摩擦副用研制的纳米锡润滑剂进行摩擦试验。用俄歇能谱仪进行了表面元素分析,用扫描电镜对摩擦涂层进行了厚度及元素分布研究。结果表明,在铜试样上形成了富含单质锡且与基体结合良好的较厚的(>10μm)摩擦涂层,从而起到磨损自修复效果。通过配方设计以及工艺优化,探索了一种能将锡活化、用较短时间在摩擦表面获得较厚涂层的方法。
Friction and wear testing was carried out on a modified MS-800 four-ball friction tester for the steel-copper tribo-pair lubricated by a new type of nanometer Tin lubricant. The surface elements were analyzed by means of Auger Electron Spectrum （AES） ,the thickness and distribution of friction coating were analyzed through Scanning Electron Microscope （SEM）. Experimental result indicates that the relatively thick （ 〉 10 μm） friction coating is formed on copper rubbing surface, which contains high content of Tin and is well combined with copper base, so that the wear-self-repairing effect is obtained. With the formula designing and technical optimizing, one method of activating Tin was explored and the relative thick coating on the friction surface was obtained in a relative short period.
