主 题：water lubrication carbon film nanostructure surface texture tribological properties
摘 要：Carbon films have been considered suitable to be applied in water lubrication since they exhibit excellent friction-reducing and wear resistance,chemical inertness,***,the basic understanding of tribological behaviors of carbon-based films under water lubrication still needs to be *** the present work,carbon films with different nanostructures were prepared by the electron cyclotron resonance(ECR)plasma nano-surface manufacturing system,and micro-textures with different sizes were prepared on the surface of carbon films by plasma *** influence of nanostructure and surface texture on the tribological properties of carbon films was *** results show that different nanostructured carbon films can obtain lower friction coefficients and longer wear life under water lubrication than under dry *** to low surface roughness,high hardness,and compact structure,the tribological properties of amorphous carbon(a-C)films under water lubrication are much better than those of graphene sheet-embedded carbon(GSEC)*** prepared surface texture has a negative effect on the hard a-C film,but it can make the soft GSEC film generate soft wear debris at the initial *** the action of water,the soft wear debris is bonded on the surface of the contacting ball to form a silt-like transfer film,which increases the wear life by nearly three orders of *** results extend the basic understanding of the tribological behavior of carbon film under water lubrication,which is crucial in both fundamental and applied science.
