摘要：

The oxidation of ZrB2-SiC and ZrB2-SiC-ZrSi2 ceramics of different composition has been studied experimentally at 1500 degrees C in pure oxygen for up to 50 h ZrB2-SiC-ZrSi2 ceramics proved to be the most oxidation-resistant at ZrSi2 contents of less then 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 ar d tested.
