摘要：
The oxidation resistance of TiAl-base alloy was attempted to increase via siliconizing. Siliconizing at 1250 degrees Celsius remarkably improved the oxidation resistance of the sample alloy. A Ti5Si3 surface layer was formed after siliconizing where a Ti-rich transition layer existed. The siliconized layer was very adherent to the substrated and neither cracked now spalled during the oxidation.
