中文摘要:
      利用非平衡磁控溅射技术在316L不锈钢基底和316L不锈钢基底喷焊Ni60C涂层表面分别制备a-C、a-C:H、a-C:Cr三种类金刚石碳基(DLC)薄膜,对比分析了不同防护体系在5 wt% H2SO4溶液中的耐磨蚀性能。结果表明:较单层DLC薄膜,Ni60C/DLC复合体系膜-基结合强度大幅提高,腐蚀磨损性能显著改善,其摩擦系数在0.05~0.14之间,腐蚀磨损率在0.66 ~ 5.7×10-8 mm3/N?m之间。Ni60C涂层作为硬质支撑层提高了薄膜的承载能力,且有效抑制了腐蚀摩擦过程中碳基(DLC)薄膜的石墨化进程,提高了Ni60C/DLC复合体系耐磨蚀性能。

英文摘要:
      Three kinds of diamond-like carbon-based films of a-C, a-C:H and a-C:Cr were deposited by unbalanced magnetron sputtering technique on 316L steel and Ni60C spray-welding coating, respectively. Tribocorrosion resistance in 5 wt% sulfuric acid solution of two different protective systems were investigated. The result indicate that the carbon-based films deposited on Ni60C spray-welding coating show a significant improved adhesion and wear resistance compared with the one deposited on 316L. The friction coefficient and corrosion wear rate of the DLC films deposited on Ni60C spray-welding coatings were 0.05 ~ 0.14 and 0.66×10-8 ~ 5.7×10-8 mm3/N?m, respectively. The improvement of abrasion resistance of composite system was attributed to the Ni60C spray-welding coating as a hard support layer which can improve the bearing capacity of the DLC films, the graphitization process of DLC films in the process of tribocorrosion test was effectively inhibited.
