Experimental analysis and research ofpulsed fiber laser polishing Ti6Al4V

Aiming at the many problems of parameters in the process of pulsed laser polishing Ti6Al4V,the improved single factor experimental scheme was used to simplify the experimental process,and to explore the influence of laser power density,frequency and initial surface morphology of the material on the polishing process.Through the observation of the surface topography,the microscopic phenomena and causes of the material surface under different parameters during the polishing process were explored.The oxidation degree of material surface under different parameters is investigated by energy spectrum analysis.Through roughness detection,the degree of roughness reduction under different parameters and initial topography is obtained.The above experimental results show that under the reasonable laser parameter setting and the use of reasonable initial surface topography of the material for laser polishing,although the content of titanium element decreases,it can effectively improve the surface quality of titanium alloy and reduce the coarseness by about 93%.
