Abstract

The present study focuses on the dynamic oxidation resistance of five representative ZrB₂-SiC based ultra-high temperature ceramics (UHTCs): ZrB₂-SiC, ZrB₂-SiC-Si₃N₄, ZrB₂-SiC-TiB₂, ZrB₂-SiC-HfB₂ and ZrB₂-SiC-ZrC using oxyacetylene torch and arc jet testing. The effects of second phase incorporation (Si₃N₄, TiB ₂, HfB₂, ZrC) on oxidation resistance were compared and analyzed. The mechanism of oxidation based on experimental results and thermodynamic calculations were explored. Some approaches to improvement of oxidation resistance and future directions of UHTC are also presented.
