To prepare exhaustion of oil supplies,alternative lubricant which is good for environment will be required.Water is expected to be a suitable lubricant.However in water lubrication,high wear and seizure come to be problems because of water's low viscosity.Surface texturing is reported to improve these problems.So in this paper,effects of surface brush structure and wettability are investigated expecting improvement of water lubrication.Four kinds of polytetrafluoroethylene(PTFE) specimen were prepared; flat specimen,hydrophilized flat specimen,brush specimen and hydrophilized brush specimen.The result of friction tests showed hydrophilized brush specimen was effective to decrease friction coefficient in the beginning of friction.The friction decreasing is considered to be caused by eliminating wear particles,water-holding and supplying water to sliding surfaces at brush area.
