Abstract:316 stainless steel was chosen as the material of the rotary ring of the test friction pair,and three kinds of polymer materials such as Thordon SXL,Yanli PREM and Yanli UNIV as the materials of the static rings of the pair respectively.The influence of pit surface texturing arrangement form on the friction coefficient and wear mass loss of three kinds of friction pair materials under water lubrication was evaluated with frictionwear tests in order to select the suitable texture layout and polymer materials of the pairs.The test results show that when both hard material and soft material are used as the friction pairs,the texture should be arranged on the soft material so as to prevent the convexity of the soft material from being embedded into the texture of the hard material,reduce the friction and wear of the friction pairs and improve the lubrication conditions.When the surface texture is arranged on the soft material sample,the friction coefficient is also the smallest under water lubrication.Yanli UNIV has the best tribological properties among the three kinds of polymers studied.
