Abstract
Aiming at the defects such as cracks in the polishing process of aluminum alloy 5052, the laser polishing of aluminum alloy 5052 was studied, and a new top-hat beam laser polishing method was proposed for aluminum alloy 5052. The energy distribution in the polishing process was well-distributed, which greatly improved the energy utilization efficiency and reduced the surface roughness. Confocal microscopy and SEM were used to obtain the microstructure and phase composition of the microstructures. The results showed that the surface roughness was considerably reduced to lengthen the service life of the aluminum alloy 5052 materials from an initial roughness of Sa = 3.9 μm to Sa = 1.32 μm after using top-hat fiber laser polishing.
