Oxidation rate of NbSi2 coating increased with temperature at 1000-1300 degrees C but opposite trend was observed at 1300-1450 degrees C. Maximum oxidation rate was obtained at 1300 degrees C due to the highest porosity of oxide scale. Lowest oxidation rate was observed at 1450 degrees C due to formation of dense oxide scale by combined effect of volatilization of Nb oxide phase, viscous flow and densification of c-SiO2. Oxidation resistance of NbSi2 coating at these temperatures was governed by some inter-related factors.
