摘要：

The response of Ti3SiC2, Ti3AlC2, Ti2AlC and Cr2AlC MAX phases under simulated primary water has been explored for the first time. Samples were tested for 28 days in 300 degrees C water with the addition of 2 ppm LiOH. The Ti-based MAX phases formed oxides of TiO and TiFeO3. X-ray diffraction and scanning electron microscopy showed no evidence of a passive Al or Si-based layer forming during testing. A-layer dissolution was observed to cause delamination of the layered structure. In contrast, Cr2AlC showed little change during autoclave testing, suggesting that a thin passivating chromia layer was formed.
