Cold roller surface is modified by laser texturing with high-energy density,high-frequency pulse laser and scheduled surface micro-topography and distribution is achieved.The roller is a major component for the production of high-quality steel sheet,and the surface topography,punching and painting performance of the steel sheet is largely determined by the surface micro-topography and wear properties of the roller,therefore,study on the topography will be important.Three main parameters,surface roughness Ra,peak density Pc and waviness Wa,are used for the characterization of the morphology of the roller surface currently,however,these parameters are not connected with the functional properties of the surface,the effect of surface micro-topography on the frictional behavior of the roller and the steel sheet can not be represented by the parameters.
