Magnesium alloy (AZ31B) was irradiated in air using a pulsed KrF excimer laser. The surface of the irradiated magnesium exhibited a wavy topography and its surface roughness was found to depend on the laser power density. The corrosion behaviour of the laser-treated magnesium was studied and it was found to be slightly better than that of the untreated magnesium.
