초록

The corrosion of metal specimens was analyzed in this study using laser-induced breakdown spectroscopy. The samples used in the study were magnesium alloys and corrosion, and standard specimens were prepared and analyzed using surface and depth analysis. The spectral wavelengths used in the oxide layer analysis were 777.196 nm, 777.421 nm, and 777.543 nm. The spectral line of the surface corrosion was confirmed by experimentation, and surface micro morphology analysis was performed using an optical microscope. Approximately $100{\mu}m$ corrosion depth was confirmed via laser irradiation in the depth direction. The results of laser-induced breakdown spectroscopy and the SEM-EDS analysis were compared and analyzed.
