摘要
采用磨削和刮研方法加工了2种表面形貌,并在乏油情况下进行了这2种形貌的最大静摩擦力实验。结果表明,刮研形貌的最大静摩擦力较磨削形貌小,约为后者的77%。且刮研表面有鱼鳞状浅坑形貌,实验观察到小气泡在刮研形貌上的浅坑中稳定存在。分析认为,该小气泡在一定的条件下有助于承载并减小最大静摩擦力。
Two kinds of surface topography of scraped and milled were made respectively, the experiment was done in oil-starved condition to test their maximum static friction. The result shows that the scratched surface has less static friction than the milled surface by 23%. The scraped surface has some fleet-pit topography ,some little bubbles stay in the fleet-pit steadily ,and these bubble can promote the load capability and reduce the static friction.
