N2 - Cyclic oxidation tests of NiCoCrAlYTa coatings were carried out at temperatures of 1173 and 1273 K by 100 cycles. NiCoCrAlYTa coatings with initial microstructure formed by typical lamellar-splat were previously manufactured by combustion flame spray. A kinetic analysis revealed parabolic behaviour during oxidation of the NiCoCrAlYTa coatings. After oxidation treatment, scanning electron microscopy and x-ray diffraction analysis showed that alumina and Ni, Cr spinels oxides were formed in the coating. The NiCoCrAlYTa coatings obtained by CFS, shown to have important oxidation resistance at high-temperature.
