In order to solve the problem of lubrication failure caused by lubricating oil migration and the interrupt of lubricating oil on contact surface,the gradient surface of oleophobic-oleophilic-oleophobic with high oil collecting performance was prepared.A layer of monolayer film was deposited on the surface of silicon wafer by chemical vapor deposition method,and the sample was characterized by contact angle measuring instrument,UMT friction and wear tester,confocal microscope,etc.The lubrication performance of this surface was studied under the condition of limited oil supply.It is found that the oil droplets can move rapidly from the oil-phobic region to the oil-wet region when the oil drops are placed at the oil-phobic/oil-wet junction.The experimental results of point contact reciprocating friction show that the friction coefficient of the silicon wafer with gradient surface is significantly lower than that of the original silicon wafer,and the wear mark depth of the silicon wafer with gradient surface is shallower than that of the original silicon wafer.Various experimental results show that the prepared oil-phobic-oleophilic-oleophobic gradient surface can play the role of oil collection and avoid the problem of lubricating oil interruption.
