Abstract
Cr2AlC has excellent oxidation resistance, thermal shock resistance, and crack healability, making it a potential candidate for use in high temperature applications. So far work on the high temperature ablation properties of Cr2AlC has been less focused. This work firstly demonstrated the high temperature ablation behavior of Cr2AlC through the oxyacetylene torch testing. The linear and mass ablation rates were determined. The microstructure and the phase composition of the ablated samples were characterized with scanning electron microscopy and X-ray diffractometry. This work provided a basic understanding of the high temperature corrosion mechanism of Cr2AlC.
