چکیده انگلیسی
The morphologies of roll surfaces are modified with pulsed Nd:YAG laser and characterized by a topography measuring instrument. Sombrero shaped bumps with diameters 230-250 μm and heights 2-4 μm are produced by defocused laser beam. Qualitative analysis of bump formation is performed. The relationship between the laser processing parameters and the profile of the bump is studied. The method of mathematical statistics is introduced to analyze the profiles of roll surface roughness. Furthermore, The measurement and analysis on the surface roughness and hardness are carried out. The results show: the bump has higher hardness than the matrix, which is adapted to the requirements of laser texturing.
