研究了低温离子硫化处理后的W掺杂类金刚石(W-DLC)薄膜的微观结构和减摩性能。根据我们的设计思想，成功地在W-DLC薄膜上制备了厚度约为100 nm的梯度分布的WS2固体润滑层。用X射线光电子能谱(XPS)和拉曼光谱对其结构进行了分析。利用纳米压痕机和球盘摩擦磨损试验机测试了材料的力学性能和摩擦学性能。结果表明，在硬质W-DLC膜上形成一层含量较低的WS2软化层和少量的SP(2)-C相，对改善DLC膜的减摩性能具有重要的作用。(C)2012爱思唯尔B.V.保留所有权利。
The microstructure and friction-reducing performance of W doped diamond-like carbon (W-DLC) film treated by low temperature ion sulfuration was investigated in this paper. According to our designing thought a solid lubrication layer of WS2 with gradient distribution and about 100 nm depth was successfully prepared on the W-DLC film. The structural analyses were performed using X-ray photoelectron spectroscope (XPS) and Raman spectroscope. The examinations of mechanical and tribological properties were completed using a nanoindenter and ball-on-disk friction and wear tester. The results showed that a soft layer of low content WS2 and a slight increase of sp(2)-C phase on the hard W-DLC film played an important and beneficial role for improving the friction-reducing performance of DLC film.
