在钢辊和正齿轮副上开发了经过和不经过自由基渗氮预处理的厚度为 3 和 10 μM 的类金刚石碳 (DLC) 涂层。在真空和油润滑的滑动滚动接触条件下评估摩擦系数和磨损量。在基材的界面处观察到涂层分层。涂层的耐磨性随着涂层厚度的增加而提高。在真空中，经过自由基渗氮处理的10μm涂层厚度的滚子和齿轮副表现出相同的磨损行为。自由基渗氮似乎可以提高 DLC 涂层的寿命。 (C) 2010 Elsevier Ltd. 保留所有权利。
Diamond-like-carbon (DLC) coating of thickness 3 and 10 mu M were developed with and without radical nitriding pretreatment on steel rollers and spur gear pair. The friction coefficient and wear amount were evaluated under sliding rolling contact condition in vacuum and under oil lubrication. Delamination of coatings was observed at the interface of the substrate. The wear resistance of coatings improved with the thickness of the coating. In vacuum both the roller and the gear pair of 10 mu m coating thickness with radical nitriding showed identical wear behavior. The radical nitriding seemed to enhance the life of DLC coatings.
