Laser Surface Treatment for Anodizing Process of Aluminum Alloy


Laser material processing play important role to improve surface properties, in this work Aluminum AA1100 was used to build Al2O3 oxide layer on the main surface of the workpiece in H2SO4 acid at cell potential between 8-24 volts for 30 minutes after irradiated the surface test by pulsed Nd-YAG laser, fluctuating current wasmeasured with time without laser treatement and after laser treatment, Pulsed Nd- YAG laser was used to test the resistance oxide layer to break. This paper gives results of the experimental research referring to the quality of surface indicator obtained by laser surface treatment.
