Abstract

A computational model for laser-induced Wagner oxidation processes on a vanadium metal surface is described and compared with the experiment. It is found that for thin oxide layers, the oxide is nearly transparent and the metal temperature rapidly increases. For thicker layers, the oxide is nearly opaque and the metal temperature slowly decreases. The Wagner rate law is found to hold for thicker oxide layers, but not at the beginning of the process.
