Abstract: Ti2AlN has been focused by many researchers for its excellent properties, however, the research on fabrication and properties of the Ti2AlN film is little. Multi-arc ion plating and subsequent vacuum annealing are used to prepare the Ti2AlN film, and the corrosion resistance and high temperature oxidation resistance of the film are tested and analyzed. The results show that the Ti2AlN film which possessed better corrosion resistance and high temperature oxidation resistance compared with TiN film can be obtained under the optimized process. The anti-oxidation limit of Ti2AlN film is 800℃ compared with 500℃ of TiN film, the continuous and dense Al2O3 formed on the surface of Ti2AlN film is the main reason for higher anti-oxidation property. The larger thermal stress between the substrate and the oxide layer when the temperature exceeded 800℃ accelerate the stripping of the oxide layer. Ti2AlN film with excellent corrosion resistance and high temperature oxidation resistance could be fabricated by multi-arc ion plating and vacuum annealing process, which can provide the theoretical support for the study of Ti2AlN film.
