Spalling of protective oxide scales

  • D. P. Whittle


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 AOv 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.
