| 英文摘要 | Type I hot corrosion behavior of SiO2-Al2O3-glass composite coating based on Ti-47Al-2Cr-2Nb substrate was investigated in the mixture salt of 25wt%NaCl+75wt%Na2SO4 at 850 degrees C. The results showed that there was a bidirectional ion exchange between composite coating and the film of mixed salts, and the sodium ion in the molten salts penetrated into the glass matrix of composite coating, while the potassium ion in the glass matrix dissolved into the molten salts. A decrease in hot corrosion rate was achieved for the coated alloy in comparison with the bared substrate due to the composite coating acting as a diffusion barrier to sulfur and chlorine and preventing the molten salts from diffusing to the coating/alloy interface during the hot corrosion exposure. Additionally, the composite coating decreased the oxygen partial pressure at the coating/alloy interface and promoted the selective oxidation of Al to form a protective Al2O3 layer. |
