为了探讨粘结石墨基固体润滑涂层的微动摩擦磨损性能的作用机理，使用SRV微动摩擦磨损试验机对粘结石墨基固体润滑涂层在微动试验条件下的摩擦学性能以及抗承载能力进行研究，对其磨痕形貌和对偶转移膜进行分析。研究结果表明：粘结石墨基固体润滑涂层的磨损率随着试验载荷和摩擦速度的增大而减小；而摩擦因数随着试验载荷增大而减小，随摩擦速度增大而缓慢增大；在微动摩擦过程中，高载高速可以促进高质量转移膜在对偶表面形成，从而使得粘结石墨基固体润滑涂层具有良好的抗承载能力和优异的抗磨减摩性能。 |

In order to research into the mechanism of the fretting friction and wear properties of bonded graphite solid lubricating coatings, the tribological properties and load-carrying capacity of the coatings were investigated by SRV fretting friction-wear tester. The morphologies of the worn surface and the transfer films of bonded graphite solid lubricating coatings in opposite parts was studied. The results show that the wear rate of bonded graphite solid lubricating coating decreases with the increase of velocity and load, whereas the friction coefficient decreases with the increase of load, and increases slowly with the increase of velocity. The high load and velocity can promote the formation of the free transfer films in opposite parts under fretting friction condition, so the bonded graphite solid lubricating coatings show high load-bearing capacity, fine antifriction and antiwear properties. |
