摘要	The NiAlTa system has been identified as a possible candidate for a protective coating material for single crystal superalloy blade tips. The microstructural evolution and elemental interdiffusion behaviour of NiAlTa/DD5 diffusion couples at 1000 degrees C, 1050 degrees C, and 1100 degrees C were investigated. Significant elemental interdiffusion occurred between the NiAlTa alloy and DD5 alloy. gamma'-Ni3Al, AlNi2Ta, and TCP phases were generated in the NiAlTa/DD5 diffusion couples. Ni had the highest average effective interdiffusion coefficient and the lowest diffusion activation energy, while the opposite was true for Ta. The precipitation of the TCP phase raised the potential for cracking in the substrate.
