Abstract

The effect of Y₂O₃ on the oxidation resistance of Nb-Ti-Si based alloys was investigated. Acicular Y₂O₃ is generated with Y content exceeding 0.3 at%. Oxidation tests reveal that the mass gain per unit area of the Y-containing alloys is lower than that of the Y-free alloy at 800 °C and 1200 °C. The oxide layer of the Y-free alloy will fracture and even pesting. After adding Y, the Y₂O₃ can react with Nb₂O₅ and TiO₂ to generate YNbTiO₆. The pinned YNbTiO₆ at the interface enhances the adhesion between the oxide layer and substrate, slowing down the growth of the oxide layer.
