This study concerns laser cleaning technology and its impact on copper corrosion resistances. The results of the treatment process were analyzed after irradiation at various laser powers and scanning velocities of the laser beam. The corrosion resistance of copper sheets, before and after laser irradiation, was examined in an NaCl solution at room temperature. Investigations included surface topography observations using a scanning electron microscope (SEM) together with chemical and phase composition determined by energy dispersive X-ray spectrometry (EDS) and Raman spectroscopy.
