Synthesis of hydrogenated DLC film by PECVD and its tribocor

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.
