主　　题：natural porous material oil infusion treatment fluorination frictional behaviors 

摘      要：Natural materials tend to exhibit excellent performance in the engineering field because of their structure and special functions.A natural red willow,called natural porous wood material(NPWM),was found,and wear tests were conducted to determine its potential as an oil-impregnated material by utilizing its special porous *** treatment was adopted to improve the NPWM properties for absorbing and storing lubricating *** different contributions of soaking and fluorination-soaking treatments on the tribological properties of NPWMs and their respective mechanism of effect were *** results showed that the fluorination-soaking treatment helped absorb and store sufficient lubricating oil in the NPWM porous structure;therefore,more lubricating oil would be squeezed out and function as a tribol-film between contacting surfaces during the friction process,thus ultimately contributing to stable and smooth wear responses even under prolong ***,the formation of an oil-in-water emulsion,caused by the buoyancy effect,destroyed the oil films on the worn NPWM surface in a water environment,resulting in higher coefficients of friction(COFs)under water conditions than under dry friction,even after the fluorination-soaking *** knowledge gained herein could not only verify the potential of NPWM as an excellent oil-impregnated material in the engineering field but also provide a new methodology for the design of artificial porous materials with stable and smooth friction processes.
