研究了SiC含量对BN-ZrO2-SiC复合材料在1600℃钢水中腐蚀后的耐腐蚀性和微观结构演变的影响。 BN-ZrO2-SiC复合材料的耐腐蚀性随着SiC含量的增加而降低。当SiC含量超过15vol%时，腐蚀速率开始急剧加快。重新烧结的 ZrO2 双层结构显着降低了腐蚀层的孔隙率，从而显着提高了耐腐蚀性。因此，优化SiC含量和调整残余腐蚀层的微观结构特征是提高BN-ZrO2-SiC复合材料耐腐蚀性能的有效途径。
The influence of SiC content on corrosion resistance and microstructural evolution of BN–ZrO2–SiC composites after corrosion in molten steel at 1600°C has been investigated. The corrosion resistance of BN–ZrO2–SiC composite decreases with increasing the SiC content. When the SiC content is more than 15 vol%, the corrosion rate begins to accelerate sharply. A resintered ZrO2bilayer structure with a distinctly reduced porosity in the corrosion layer contributes significantly to the enhanced corrosion resistance. Thus, optimizing the SiC content and tailoring the microstructural feature of residual corrosion layer are effective ways to improve the corrosion resistance of BN–ZrO2–SiC composite.
