| 摘 要： | 采用磁控溅射技术在高速钢和单晶硅基体制备了不同碳含量的CrTiAlCN复合镀层,利用XRD、XPS、SEM分析了镀层的相结构、元素存在状态及截面显微形貌,通过销-盘式摩擦磨损试验机研究了镀层的摩擦系数。结果表明,镀层主要由CrN结构的化合物相组成;随着碳含量的增加,镀层中的sp2碳键含量增加,镀层逐渐开始非晶化,镀层更加致密。镀层的摩擦系数随碳含量的增加而下降,当碳含量为50.47 at%时,镀层摩擦系数降至0.1。

| Abstract: | Influence of carbon content on microstructure and frictional behavior of CrTiAlCN coatings,which was deposited on high speed steel and silicon wafer substrates by magnetron sputtering,was studied.The phase,elementary state and cross-section morphology of the CrTiAlCN coatings were analyzed by XRD,XPS and SEM,respectively.Friction coefficient of the coatings was studied by a pin-on-disk tester.The results show that the mainly phase of coatings is CrN.With the increase of carbon content,sp2 carbon bond of the... |
