摘要	The effect of enamel coating on long-term isothermal oxidation at 700 V and cyclic oxidation at 800 degreesC in air and hot corrosion resistance of Ti-24Al-17Nb-0.5Mo in 75% (Na2SO4 + K2SO4) + 25% NaCl (mass fraction) molten mixed salts at 700 degreesC was investigated. The results indicate that Ti-.24Al-17Nb-0.5Mo alloy exhibits relatively poor long-term oxidation resistance due to the formation of Al2O3 + TiO2 + Nb2O5 mixed scales and poor hot corrosion resistance due to the spallation of scales formed in molten (Na, K)(2)SO4 + NaCl. Enamel coating can effectively protect Ti-24Al-17Nb-0.5Mo alloy from long-term oxidation at high temperature in air and remarkably improve the hot corrosion resistance of Ti-24Al-17Nb-0. 5Mo alloy, and can act as the barrier to suppress the migration of oxygen and corrosive ions into the substrate.
