Experimental Investigation of the Friction and Wear Characteristics of Engineering Plastics under Water Lubrication
Appropriate selection of materials for the friction pairs of the water hydraulic elements is crucial to improve the performance features. The friction and wear characteristics of three kinds of engineering plastics, including polyetheretherketone (as PEEK), ultra high weight molecular polyethylene (UHWM-PE) and carbon fiber reinforced phenolic resin (F102) were investigated on a general-use test machine. The effects of normal load and sliding velocity on the friction coefficients were studied. The counter parts were either made of stainless steel 17-4PH or plasma sprayed with a layer of Al2O3,·20％TiO2. It is found that among all the material combinations, PEEK demonstrates comparatively low friction and wear, while UHWM-PE has the lowest friction coefficients and highest wear rate, and F102 falls between. In general, under water lubrication, the friction and wear of F102 and PEEK is closely related with load and sliding velocity, especially under high load and velocity..
