Experimental Study on Surface Texture and Coefficient of Friction in Sliding Friction Test

摘要

This paper describes the experimental results of relationship between topological indices of surface texture and coefficient of friction in machined surface. Firstly the definitions of topological indices based on the linear material ratio curve are explained. Secondly the experimental results in the reciprocating sliding friction test are mentioned. The following remarks were obtained. 1) The coefficient of friction in a surface texture with wide dimple area trends to be smaller than that with small dimple area. 2) The coefficient of friction seems not to be affected by the relative moving direction of reciprocating sliding friction test.
