Abstract

We propose a non-destructive measurement method to identify Al ₂ O ₃ scale on an Fe–Al alloy and to evaluate the morphology and thickness of the scale using cathodoluminescence (CL)and X-ray-excited optical luminescence (XEOL). CL and XEOL images allowed us to distinguish the Al ₂ O ₃ scale from other scales from the luminescent color of the Al ₂ O ₃ , and to observe the surface morphology of the scale. The CL intensity of a peak at 695 nm in the spectra was used to determine the scale thickness. Therefore, CL and XEOL analysis could be used in the non-destructive evaluation of oxide scales on heat-resistant steels.
