Densification and oxidation behavior of a novel TiB2-MoSi2-CrB2 composite

► High dense composites (> 96% TD) of TiB2 + CrB2 + MoSi2 were prepared. ► The nature of oxidation of the composite was parabolic at 750 and cubic at 850 °C. ► Formation of a continuous and protective thick glassy phase was seen with 15% CrB2. ► This composite is found to be a more oxidation resistant material. ► B and Si diffuse towards the surface during the high temperature oxidation.
