| Popis: | The oxidation behavior of Zr2[Al(Si)]4C5/30 vol.%SiC composite(ZASC-30SC) at 900–1300 °C was investigated, and the effect of SiC additive on the oxidation resistance of Zr2[Al(Si)]4C5 at 1000 °C is negative. A boronizing coating containing ZrB2 and SiC was prepared through boronizing treatment. The effect of boronizing on the oxidation resistance of ZASC-30SC composite at 1000 °C and 1800 °C were explored respectively. At 1000 °C, the oxidation resistance was improved intensively as a result of a protective liquid B2O3 containing scale formed during oxidation. Besides, the oxidation properties at 1800 °C of ZASC-30SC was improved obviously because of a protective SiO2 rich layer generated. |
