Vapor-phase mechanism of the laser oxidation of metals
Abstract
Based on an analysis of experimental results obtained for D16 Duralumin specimens, a model is proposed for the oxidation of metals irradiated by short laser pulses. The oxidation process involves metal evaporation, its oxidation in the vapor phase, onset of a backflow of oxide molecules, and their condensation and additional oxidation on the specimen surface. This oxidation mechanism, which has been observed for copper, aluminum Duralumin, and titanium, is also valid for nonmetallic materials, such as superconductors.
