摘要: 本文研究了Mo/Ni3Al复合材料的抗氧化性能.结果指出,Mo/Ni3Al复合材料在不同温度下的氧化动力学特征服从抛物线规律.随氧化试验温度升高,氧化增重明显增加.MoO2在高温下被氧化成MoO3,对Mo/Ni3Al复合材料的抗氧化性能具有不利的影响.Abstract: The oxidation resistance of Mo/Ni3Al composite has been studied. The results show that the oxidation kinetics of Mo/Ni3Al composite at different temperatures obeys the parabolic law. The amounts of oxide increase obviously with that of the experimental temperature.MoO2 being oxidated to MoO3 at high temperature results in the decreasing of oxidation resistance of Mo/Ni3Al composite.
