Oxidation of ZrB2–SiC–ZrSi2 ceramics in oxygen
The oxidation of ZrB2-SiC and ZrB2-SiC-ZrSi2 ceramics with different compositions was studied at 1500 C in pure oxygen for up to 50 h. ZrB2-SiC-ZrSi2 ceramics were the most oxidation-resistant at ZrSi2 contents of < 4 wt%. These ceramics were more oxidation-resistant than ZrB2-SiC ceramics. An an...

Summary: | The oxidation of ZrB2-SiC and ZrB2-SiC-ZrSi2 ceramics with different compositions was studied at 1500 C in pure oxygen for up to 50 h. ZrB2-SiC-ZrSi2 ceramics were the most oxidation-resistant at ZrSi2 contents of < 4 wt%. These ceramics were more oxidation-resistant than ZrB2-SiC ceramics. An analytical model of growth kinetics for a multilayered scale based on an oxidation-diffusion balance was developed and tested. |
