Theoretical Analysis of the Diffusion Processes Determining the Oxidation Rate of Alloys
TL;DR: In this paper, the interplay of diffusion processes in metallic and oxide phases during the oxidation of alloys is analyzed theoretically for specified ideal conditions, and it is shown that two oxides may nucleate initially and continue to grow even under conditions under which exclusive formation of the oxide of the less noble metal is a possible process.
