| Abstract: | TiAl intermetallics are important materials for a wide variety of applications such as advanced au tomobile and aircraft engine components because of their low density,high melting temperature,and high temperature strength-However,one of the key problems is their poor high temperature oxidation resistance.This paper reviews the present status of research on high temperature oxidation resistance of TiAl,which covers various areas including oxidation mechanism of TiAl,the role of additional elements,and applications of surface technology-In addition,plasma mobizing can greatly improve the oxidation resistance of TiAl and the role of mobizmg is discussed. |
| Keywords: | TiAl intermetallics high temperature oxidation surface technology |
