Hydrogenated diamond-like carbon (DLC) film was prepared on the stainless steel by plasma enhanced chemical vapor deposition technique and its tribocorrosion behaviors under different lubricating conditions were investigated. The results show that the hydrogenated DLC film exhibits superior tribocorrosion resistance than the steel substrate in water. The addition of graphene oxide (GO) in water can further improve the tribocorrosion resistance of the DLC film. The excellent tribocorrosion resistance of the DLC film lubricated with the GO dispersed in water is attributed to the high hardness and chemical inertness of the DLC film and the deposited film of GO nanosheets on the wear surface that has lubrication function for reducing wear and acts as barrier layer against corrosion during rubbing process.
