利用实验室自制的原位拉曼摩擦磨损试验机研究了MoDTC溶液润滑下氢化非晶碳（a-C：H）薄膜的结构转变。特别是，我们旨在揭示DLC膜与MoDTC溶液润滑的磨损加速。结果表明，MoDTC衍生化合物与DLC膜表面发生化学反应生成Mo碳化物所引起的化学磨损和化学反应生成的Mo碳化物颗粒所引起的磨粒磨损是MoDTC润滑DLC膜磨损加速的主要原因。
The structural transformation of a hydrogenated amorphous carbon (a-C:H) film lubricated with MoDTC solution was investigated using a laboratory-builtin situRaman tribometer. Especially, we aimed to reveal the wear acceleration of DLC films lubricated with MoDTC solution. All our results suggest that the main reasons of wear acceleration of DLC films lubricated with MoDTC solution are the chemical wear caused by chemical reactions between the MoDTC-derived compounds and DLC surfaces to produce Mo-carbides and the abrasive wear caused by Mo-carbides particles produced by the chemical reactions.
