| 摘 要： | 研究了保护渣对Ｏ’－Ｓｉａｌｏｎ－ＺｒＯ２复合材料的侵蚀情况，并与ｔ－ＺｒＯ２材料对比。结果表明．保护渣对ｔ－ＺｒＯ２的侵蚀小于Ｏ’－Ｓｉａｌｏｎ－ＺｒＯ２材料；ＺｒＯ２引入量的增多，有利于Ｏ’－Ｓｉａｌｏｎ－ＺｒＯ２制品抗渣性能的提高。这可能是由于ＺｒＯ２在保护渣中的溶解度较小，渣中ＣＯ与Ｏ’－Ｓｉａｌｏｎ的反应及渣中多元成分与Ｏ’－Ｓｉａｌｏｎ共同作用的结果。

| Abstract: | Investigations on the corrosion of concast protective slag on O'-Sialon-ZrO2 composite specimens have been carried out together with a Y2O3-stabilized t-ZrO2 specimen for comparison. The results have shown that the corrosion on t-ZrO2 material is slighter than on the composite specimens. The increase of ZrO2 content leads to improve the slag resistance of the O'-Sialon-ZrO2 product. This is due to the combined effects of lower solubility of ZrO2 in protective slag and more active reaction between O'-Sialon and slag and CO. |
