Abstract

Pulsed laser irradiation of thin metal films sputtered onto a magnesium alloy substrate produces surface compositions which exhibit improved pitting corrosion resistance to aqueous chloride ion relative to untreated magnesium. Preliminary results suggest a relationship between the composition of the laser produced surface plasma, as determined by atomic emission spectroscopy, and the corrosion properties of the laser melted magnesium surface. A photoacoustic technique for monitoring the energy deposited in a sample during laser surface treatment will also be described.
