Abstract

The bulk mole fraction of an element A in a binary alloy AB required to form (1) a coherent, continuous layer of oxide AOv, (2)a second layer of AO v should the first layer spall from the surface, and (3) further layers of the protective oxide if repeated spalling is likely, is calculated as a function of the ratio of the parabolic rate constant for oxidation to the alloy interdiffusion coefficient. The implications of spalling of the protective oxide layers are also discussed.
