Effect of Spraying Power on Oxidation Resistance of MoSi(2)-ZrB(2) Coating for Nb-Si Based Alloy Prepared by Atmospheric Plasma

The MoSi(2)-ZrB(2) 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 MoSi(2)-ZrB(2) coating at 1250 °C were studied. The results showed that the main cons...

description The MoSi(2)-ZrB(2) 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 MoSi(2)-ZrB(2) coating at 1250 °C were studied. The results showed that the main constituent phases of coatings were MoSi(2) 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 SiO(2) and ZrSiO(4).
