Laser micro-textured surfaces can be used to control and adjust friction. In general, metal-to-metal friction causes the generation and growth of wear debris in the initial stage (running-in process). The contact state changes drastically when micro-dimples are formed. For undulated surface made by laser micro texturing, it is thought that the micro-uneven surface inhibits the growth of wear particles and suppresses adhesion, and is effective in reducing friction by reducing adhesion and other factors. However, the frictional properties of undulated surfaces by laser micro texturing have not been investigated in detail. In this paper, the friction between DLC film and micro textured surface was investigated. And the effect of sliding motion patterns on the formation of the adhesion and transfer layer were also investigated.
