Oxide-scale growth on Cr2AlC ceramic and its consequence for self-healing

Outward growth of oxide scale on Cr2AlC surface during multiple annealing at 1100°C was investigated with ex situ microscopy. A dense alumina scale was formed on the surface of Cr2AlC samples after annealing for 40h. A wedge-shaped specimen with varying thickness of oxide scale was prepared by focus...
