摘要

摘要: 为了研究TiB₂-HfC陶瓷的高温抗氧化性能, 分析了TiB₂-HfC陶瓷在1100 ℃下分别氧化1、4、7、10 h后的氧化行为; 根据材料氧化后的微观结构, 对陶瓷氧化层进行了划分, 将其分为外氧化层、次氧化层及过渡层。实验结果表明: 外氧化层的氧化物为TiO₂、B₂O₃、HfO₂、NiO和CoO; 随着氧化时间的延长, 材料发生了严重氧化, 氧化层逐渐变厚, 材料保有的抗弯强度逐渐减小, 材料的氧化增重与氧化时间呈抛物线规律; 氧化1h后, 材料表面形成了约为12 μm的致密氧化层, 此时材料具有较好的抗氧化性能, 且仍保有较高的抗弯强度, 其值为823.6 MPa。

Abstract: Oxidation behavior of the TiB₂-HfC ceramic oxidized at 1100 ℃ for 1, 4, 7, 10 h was investigated to analyze the oxidation resistance of TiB₂-HfC ceramic at high temperature. According to the microstructure of TiB₂-HfC ceramic after oxidation, the oxidation layers were divided into the outer oxide layer, the sub-oxidation layer, and the transition layer. The results show that the TiO₂, B₂O₃, HfO₂, NiO, and CoO exist in the outer oxidation layer. With the increase of the oxidation time, the TiB₂-HfC ceramic is seriously oxidized, the oxide layer becomes thicker, and the bending strength decreases gradually. The oxidation gain and oxidation time were parabolic. After the oxidation for 1 h, a dense oxide layer with the thickness of about 12 μm is formed on the surface of the TiB₂-HfC ceramic. At this time, the TiB₂-HfC ceramic shows a better oxidation resistance and still has a relatively high bending strength, which is 823.6 MPa.
