This paper presents a method of laser texturing, and a new type of regular surface roughness profile has been produced on the roll surface. A series of experiments have been developed to produce regular surface roughness profiles using a Nd:YAG laser. According to the analysis of the principle of laser texturing, the laser parameters are primely selected and matched. Consequently, the predesigned surface roughness profile and size have been successfully obtained. Furthermore, The measurement and analysis on the surface roughness hardness and abrasion resistance are carried on. The results show: the surface roughness has higher hardness rather than matrix, which adapted to the requirements of laser texturing. The surface roughness also has good abrasion resistance. In addition, the influence regulations between pulsed laser parameters and main profile parameters of roll surface have been investigated.
