Title: Fretting friction and wear properties of bonded graphite solid lubricating coatings
Abstract: 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 fine 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.
