Abstract
⺠Surface stability of gamma-TiAl is in the order of (100), (111), (110), and (001). ⺠O could either adsorb or absorb in (100) surface with similar adsorption energies. ⺠The fcc-Al and hcp-Al sites are favorable sites if O adsorbs on (111) surface. ⺠O-Ti bond is stronger than O-Al bond, but a competition between them was observed. ⺠Oxidation resistance of gamma-TiAl could be improved by enhancing O-Al bonding.
