摘要
针对热态下飞灰磨损现象，用俄歇电子能谱仪（ＡＥＳ）测定了２０碳钢在２００～３５０℃范围内氧化膜的厚度变化，并用线性回归法得到了氧化膜厚度与表面温度之间的关系式，据此分析金属氧化膜厚度及性质对飞灰冲蚀磨损的影响．
The tesult of flyash erosion at high temperature is analysed.With Auger Electron Spectrometer (AES), No. 20 carbon steel surface oxide film thickness at the temperature from 200℃ to 350℃ is tested and the relationship between the oxide film thickness and the surface temperature is strdied with linear regression method. Accordingly,the effecf of the metal oxide film thickness on flyash erosion is analysed.
