Abstract: The paper indicates that high-temperature tribological property of TiAl based alloy is determined by high temperature oxidation resistance,high-temperature intensity and high-temperature self-lubricating property.The influence of component of of TiAl based alloy on high temperature oxidation resistance,high-temperature intensity and high-temperature self-lubricating property are summarized.For developing a new high temperature configurable wear resistant TiAl alloy,the designing methods are introduced.
