Abstract Cycle oxidation resistance of a nanostructured Ni60–TiB2 composite coating sprayed by high velocity oxy–fuel(HVOF) at 600oC in static air was investigated. The conventional Ni60–TiB2 composite coating was also investigated for comparison. The results show that oxide scale on the nanostructured Ni60–TiB2 composite coating consist of complete and continuous SiO2 scale, the fine uniform dispersed TiO2 particles and B2O3 scale spread on the serface of oxide scale.The oxidation process of the nanostructured and conventional Ni60–TiB2 composite coatings are controlled by a diffusion mechanism, and the nanostructured Ni60–TiB2 composite coating exhibits better cycle oxidation resistance than that of the conventional composite coating. The reasons can be attributed to the formation of the intact SiO2 protective layer, and the enhanced adhesion between oxide film and nanocrystalline coating.
