摘要/Abstract

摘要：

采用UDP650型闭合场非平衡磁控溅射系统在硅片及316不锈钢基底表面制备了不同掺杂设计的类金刚石涂层(DLC、Cr/DLC和WC/DLC),通过SEM、Raman、硬度仪和划痕仪研究了涂层的结构及力学性能,利用多功能摩擦试验机考察了涂层在大气及海水环境下的摩擦学性能。结果表明,Cr或WC掺杂能显著促进DLC涂层的石墨化,同时提高涂层的结合力及韧性。在摩擦磨损试验中,由于海水的润滑作用,3种涂层在海水环境下的摩擦因数及磨损率均低于大气环境。同时,WC/DLC在3种涂层中表现出最佳的摩擦学性能,这取决于其高的石墨化程度,良好的结合力及优异的韧性。

Abstract:

Diamond-like carbon coatings with different doping designs (DLC, Cr/DLC and WC/DLC) were prepared on the silicon wafer and 316 stainless steel substrate surface using UDP650 closed-field unbalanced magnetron sputtering system. The structure and mechanical properties of all the coatings were measured by means of SEM, Raman, hardness tester and scratch tester. The tribological performances of these coatings in the air and seawater environments were examined by friction testing machine. The results show that Cr- or WC-doping can significantly promote the graphitization of the DLC coating. Meanwhile, it can improve the adhesion strength and toughness of the DLC coating. In the friction and wear test, due to the lubricating effect of seawater, the friction coefficient and wear rate of all the coatings in the seawater environment is lower than that in the air environment. At the same time, compared with other coatings, the WC/DLC coating exhibits the best tribological properties, mainly depending on its high degree of graphitization, good adhesion and excellent toughness.

Key words: diamond-like carbon (DLC) coating, doping, adhesion force, toughness, tribological performance
