The oxidation-resistance mechanisms of multicomponent ultra-high-temperature ceramics at 1700 °C

The oxidation behavior of (HfB 2 ) 1 (ZrB 2 ) 0.5 –20 vol% SiC (HZS) and (HfB 2 ) 1 (ZrB 2 ) 0.5 (CrB 2 ) 0.25 –20 vol% SiC (HZCS) composites, prepared by spark plasma sintering, was investigated at 1700 °C in air. Relative to HfB 2 –20 vol% SiC (HS), both exhibit comparable oxid...
