Abstract

This study examined the surface texture formed by laser irradiation in sulfuric acid solution. Laser irradiation accelerated the localized corrosion in the solution, but other than laser irradiation area corroded. By applying passive potential, corrosion depth by laser irradiation was deeper than natural potential, and other than laser irradiation area did not corrode. Corrosion depth increased with increasing laser power and increasing number of scanning of laser.
