Oxidation behavior of the Y2O3 -modified aluminide coating on Ti-6Al-4V alloy
By using Y2O3 powder, instead of Al2O3, acting as filler, the Y2O3 was successfully dispersed in the outer layer of aluminide coatings. After oxidation, the transformation from Theta to alpha-alumina formed on the aluminide coatings using different fillers and the initial oxidation rate kinetics rel...

description | By using Y2O3 powder, instead of Al2O3, acting as filler, the Y2O3 was successfully dispersed in the outer layer of aluminide coatings. After oxidation, the transformation from Theta to alpha-alumina formed on the aluminide coatings using different fillers and the initial oxidation rate kinetics related to the alumina phase formed have been investigated. The results showed that the oxidation rate of Y2O3-dispersed aluminide coating in the initial 10h was about five times than that of Al2O3-dispersed aluminide coating. The tendency of the formation different alumina phases was also elucidated. |
