Promoting direct formation of a single α-Al2O3 scale on a silicon-aluminizing coating on TiAl alloys by a novel fluorination method

Metastable θ-Al2O3 rather than stable α-Al2O3 scale is preferentially formed during oxidation between 850 °C and 1000 °C, which decrease the long-term service life of the coating. In this study, a novel method for promoting the formation of single α-Al2O3 through the fluorination modification of a s...
