The scales that formed on the Ti3AlC2 were thin and rich in alpha-Al2O3, whose growth rate was exceedingly slow. The TiO2 was present either as the outermost surface scale or a mixture inside the alpha-Al2O3-rich scale. In the Ti3AlC2, the activity and diffusivity of Ti were low, whereas those of Al were high. This was the main reason for the superior corrosion resistance of Ti3AlC2 over TiAl. (C) 2011 Elsevier Ltd. All rights reserved.
