Herein, a series of Ag coatings with different micro-dimples were fabricated on copper surfaces by laser surface texturing (LST) and magnetron sputtering. Multilayer graphene lubricating grease (MGLG) was prepared using multilayer graphene as an additive. The textured Ag coatings and MGLG were characterized. Moreover, the tribological and electrical performances of the textured Ag coatings under MGLG lubrication were investigated in detail. Results demonstrated that the textured Ag coating with an appropriate dimple diameter could exhibit improved tribological and electrical properties when compared to the non-textured Ag coating under MGLG lubrication. The characterization and analysis of the worn surfaces suggest that the synergetic effect of LST and MGLG contributes to these excellent tribological and electrical properties.

本文中，通过激光表面纹理化（LST）和磁控溅射在铜表面上制备了一系列具有不同微凹痕的Ag涂层。使用多层石墨烯作为添加剂制备了多层石墨烯润滑脂（MGLG）。表征了织构化的Ag涂层和MGLG。此外，详细研究了在MGLG润滑条件下有纹理的Ag涂层的摩擦学和电气性能。结果表明，与在MGLG润滑下的非织构Ag涂层相比，具有适当凹坑直径的织构Ag涂层可以表现出改善的摩擦学和电学性能。磨损表面的表征和分析表明，LST和MGLG的协同作用有助于这些优异的摩擦学和电学性能。
