AbstractThe Al-modified MoSi2/Al2O3 coating was designed on molybdenum metal surface, and then its corrosion-resistant property was evaluated in a GTD111 superalloy. Results showed the Al-modified MoSi2 coating obtained by pack cementation was comprised of Mo(Si,Al)(2), Al8Mo3, and AlMo3. Then, the oxidation behavior of the coating at 1300 degrees C was systematically investigated to generate a protective Al2O3 scale. After casting test, corrosion behaviors of Al-modified MoSi2/Al2O3 coating without and with Al8Mo3 phase were contrasted to illustrate the mechanism resisting to the molten superalloy at 1550 degrees C. The Al8Mo3 phase and thermal shock give rise to the coating failure.
