摘要	A novel TiAl(3)-Al coating was prepared by cold spray for high temperature protection of titanium aluminum-based alloy. The substrate alloy was orthorhombic-Ti-22Al-26Nb (at.%). The composite coating was mainly composed of TiAl(3) embedded in the matrix of residual aluminum. An interlayer about 10 mu m was formed between the coating and the substrate. The oxidation test indicated that this composite coating was very effective in improving the high-temperature oxidation resistance of the substrate alloy at 950 A degrees C in the tested 150 cycles without any sign of degradation. The microstructure analysis of the oxidized composite coating showed that an Al(2)O(3) scale with a complex structure can be formed outside the interlayer during oxidation and no oxides beneath the interlayer were detected, which indicated that the complex continuous Al(2)O(3) and the interlayer provide the protection of the substrate at high-temperature oxidation condition.
