Abstract

Abstract: In order to study the effect of different water lubrication conditions on the friction process of UHMWPE/rubber composites, different UHMWPE composites with different rubber fillings were prepared by high temperature mixing and hot pressing. Using MRH-3 ring-block friction testing machine, through the control variable method, the friction and wear properties of different components of composites were quantitatively studied, so as to optimize the final UHMWPE composites. On this basis, the effect of three water lubrication conditions on the friction process of the optimal material was studied, and the wear surface was analyzed by SEM to explore the friction mechanism from the microscopic level. The results show that water lubrication conditions have a significant effect on the tribological properties of UHMWPE composites, and the corresponding wear mechanisms are different. The improvement of lubrication conditions can shorten the running-in period and lengthen the stable wear period. The wear conditions of water-lubricated bearing materials of naval vessels under different water-lubricated conditions are comprehensively evaluated from both microscopic and quantitative aspects, which can provide theoretical guidance for working condition planning and practical application.

Key words: water lubrication, UHMWPE, wear mechanism, quantitative stud
