Ti2AlN/TiN functionally graded materials (FGM) were successfully fabricated by vacuum hot-pressing. Bulk density of the sintered samples was measured by Archimedes principle. The sample sintered at 1 300℃for 2 h has the maximum final density and lowest open porosity. SEM coupled with EDS was utilized to investigate the phase composition and microstructure, and well-formed boundary was found between the layers. The microhardness tests suggest that Vickers’ hardness of Ti2AlN/TiN FGM increases monotonically with the volume fraction content of TiN increases. Corrosion results are that the corrosion resistance of Ti2AlN/TiN FGM is much better than that of Ti2AlN in acid, but quite the opposite in alkali. Constant temperature oxidation study shows that the oxidation kinetics of Ti2AlN/TiN FGM at 900 °C follows the parabolic law closely.
