Metal-DLC film is an effective way to reduce the stress and improve the mechanical properties of DLC films.
述评了金属-类金刚石薄膜的制备工艺、不同金属粒子对DLC薄膜形态、键结构、力学及摩擦磨损性能、物理化学性能等的影响,指出在金属粒子对DLC膜的力学及摩擦学性能的影响方面还有很多待确定的因素。
The structure and tribological properties of TiNx/DLC films was investigated.
采用等离子体基离子注入技术在30CrMnSi钢上制备了TiNx/DLC多层膜,通过X射线光电子谱和激光喇曼光谱测试分析了膜的结构特征,TiNx/DLC膜大气下的摩擦性能在球盘式摩擦磨损试验机上进行。
The composition, structure and properties of DLC films were investigated by spectroscopic ellipsometer, Raman spectroscopy, X–ray photoelectron spectroscopy(XPS), powder X–ray diffraction(XRD), spectrophotometer, nanoindenter, ball-on-disk tribometer, Rockwell apparatus and optical microscope.
硅片上的薄膜厚度均为37nm左右,75V、100V偏压下制得的薄膜具有最高的sp3键含量,薄膜具有典型的DLC膜Raman光谱特征。
