Abstract:

　    The capability of oxidation of 20g and ND steel at isothermal temperature of 450 ℃ w as studied , and the oxidation kinetic curves were attained.The formula of oxidation kinetic curves was draw n up , at the same time , the oxidization surface of samples was macroscopically observed and the components of oxides w ere analyzed by XRD.The results show as follows :with the increase of the temperature and the time of heat preservation , the constant of oxidation rate increases.The capability of antioxidation of 20g and ND steel decreases continually .While ND steel is oxygenated at 450 ℃, with the increase of oxidation time , oxidation weight increases, and its dynamics constant is 0.035 .Comparing with 20g steel , ND steel has better resist oxidation properties and the velocity of erosion is lower .

摘要： 　    研究20g 钢和ND 钢在450 ℃下的恒温氧化性能, 得出氧化动力学曲线, 进行氧化动力学曲线公式的拟和, 同时对氧化后的试样表面情况进行宏观观察, 用XRD 分析了氧化物的成分。实验结果表明, 20g 钢和ND 钢表面氧化的程度随着温度升高、保温时间增长, 其氧化速率常数增大, 20g 钢和ND 钢的抗氧化性能不断的降低。ND钢在450 ℃氧化时, 随着氧化时间的增加, 氧化增重加大, 其氧化动力学常数为0.035 。ND 钢与20g 钢相比, 具有较好的抗高温氧化能力, 腐蚀速率低。
