| Abstract: | TiAl alloys have specialties of low density,high specific strength,high specific stiffness,high elastic modulus,good corrosion resistance and creep resistance at high temperature.So,they become a kind of potential high-temperature structural material for the fields of aeronautics & astronautics,gas turbine and automobile industries.However,before practical application,the poor high-temperature oxidation resistance and wear resistance of TiAl intermetallics must be solved.In this paper,the latest progress on surface technology for high-temperature oxidation resistance and wear resistance of TiAl alloys is reviewed. |

| Keywords: | TiAl intermetallics high-temperature oxidation resistance wear resistance surface technology |
