TiN-Ag composite coatings were prepared by pulsed bias arc ion plating. X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS) were applied to analyze the compositions of the coatings. Tribological properties of the coatings were studied using an MFT-R4000 ball-on-disk friction tester in the presence of lubricating greases containing multilayer graphene. Scanning electron microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) were used to analyze the worn surface compositions of the lubricating films. The results show that with the decrease in Ag in the film, hardness increased but electrical conductivity decreased. The coating with 10 at% Ag content shows the best friction-reducing and anti-wear properties, which can be attributed to the moderate content of Ag embedded in the TiN crystal gap that enhanced the grain bonding force to improve the anti-wear and self-lubricating ability. Graphene can be adsorbed on the coating as a solid lubricant.

TiN-Ag复合涂层是通过脉冲偏压电弧离子镀制备的。X射线衍射（XRD）和能量色散X射线光谱（EDS）用于分析涂层的组成。在含有多层石墨烯的润滑脂存在下，使用MFT-R4000圆盘摩擦试验仪研究了涂层的摩擦学性能。扫描电子显微镜（SEM），拉曼光谱和X射线光电子能谱（XPS）用于分析润滑膜的磨损表面成分。结果表明，随着薄膜中Ag含量的减少，硬度增加，但导电性降低。银含量为10 at％的涂层具有最佳的减摩和抗磨性能，这可以归因于嵌入TiN晶体缝隙中的Ag含量适中，从而增强了晶粒结合力，从而提高了抗磨性和自润滑能力。石墨烯可以作为固体润滑剂吸附在涂层上。
