| 摘 要： | 使用实验的方法研究了大气等离子喷涂(APS)热障涂层在4种不同高温环境下的氧化层生长规律,并且使用目前常见的两种氧化层生长动力学曲线方程拟合了涂层氧化的实验数据,分别得到了相应的方程特征参数值.研究结果表明:APS热障涂层在所研究的4种温度下的动力学曲线形式上是一致的;抛物线形式的动力学方程只能描述较高温度下的氧化层生长规律,而幂函数形式的动力学方程对氧化温度的适应能力比较强,能很好的描述在所研究的4种温度下APS热障涂层的生长规律.

| Abstract: | The experiment method was adopted to study the oxidation kinetics of air plasma sprayed(APS) thermal barrier coatings(TBCs) in four different temperatures,and the state parameters were given by matching the experimental data with these two popular oxidation kinetics formulas.The investigation shows that the kinetic curves are the same in the form under four different temperatures,and the oxidation kinetics of APS TBCs can be expressed properly by the parabolic function formula only under higher temperatures... |
