Abstract
The MoSi2-ZrB2 coatings were prepared on Nb-Si based alloy by atmospheric plasma spraying with the spraying power 40, 43 and 45 kW. The effect of spraying power on the microstructure and oxidation resistance of MoSi2-ZrB2 coating at 1250 °C were studied. The results showed that the main constituent phases of coatings were MoSi2 at all spraying power. The coating became more compact as the spraying power increased. The coating prepared at 45 kW was dense and uniform, which exhibited the best oxidation resistance due to the formation of a dense and uniform glass layer consisting of SiO2 and ZrSiO4.
