Popis:	In this study, the surface of 6082 aluminum alloy was machined by laser heat treatment, and the microstructure and properties of the affected zone of laser surface were discussed by scanning electron microscope (SEM). The experimental results show that the laser treatment has an obvious second phase fine grain strengthening effect on the surface of aluminum alloy. The local hardness of the surface laser action zone has been improved obviously. Combined with the polarization curve data and microscopic corrosion morphology, with the addition of laser, the corrosion resistance mechanism of aluminum alloy has been well optimized, and the number and continuity of pitting pits on the surface of aluminum alloy have been restrained. The intergranular corrosion and the maximum corrosion depth behavior decreased under the corrosion of Cl−. The comprehensive properties of aluminum alloy surface have been effectively optimized under the action of laser heat treatment.the effect of laser heat treatment on the corrosion resistance and the surface mechanical properties of AA6082 aluminum alloy was investigated.
