Oxide Scale Growth on Cr2AlC Ceramic by Ansar Hayat is a document available to read on EtoBox.
The study investigates the growth of oxide scale on Cr2AlC ceramic during multiple annealing at 1100 °C, revealing that the outward diffusion of aluminum ions via grain boundaries is the primary mechanism for oxide scale growth. A dense alumina scale forms after 40 hours of annealing, which is crucial for the self-healing kinetics of exposed cracks in MAX phase ceramics. The findings suggest that the thickness of the oxide scale significantly impacts the self-healing efficiency, with thinner scales allowing
