Oxidation of Hot Pressed Cr2AlC Compounds at 900-1200℃ for Up to 50 Hours in Air Lee, Dong-Bok;
compounds were synthesized by hot pressing, and oxidized between 900 and in air for up to 50 hours. They oxidized to a thin layer containing a small amount of with the liberation of carbon as CO or gases. The consumption of Al to form the layer led to the depletion of Al and enrichment of Cr just below the layer, resulting in the formation of an underlying layer. As the oxidation temperature and time increased, the oxide layer and the underlying layer thickened. The oxidation resistance of was generally good due to the formation of the barrier layer.
