低合金耐热钢钢（研）102氧化膜结构及形成机理的研究

On the Oxidization Film Structure and the Formation Mechanism of Steel （study） 102

本文着重于火电厂蒸汽管道常用的耐热钢钢（研）102这种低碳低合金耐热钢，通过扫描电镜、能谱分析和X射线衍射分析来研究其氧化膜的形貌结构、形成过程，氧化膜的成分以及物相结构等问题，为高温高压氧化腐蚀问题提供一些基础性的研究．为减少因氧化产生的蒸汽管壁厚减薄而发生的爆管问题提供参考，这些对于火电厂来说都具有重要的理论和实用价值。

In this paper, steel（study）102 which is working in steam pipes in thermal power plant are researched. The microstructure, form process, composition, and phase structure of the oxide film are analyzed by SEM, EDS and TEM. It makes a contribution to the basic research on the oxidation and corruption in high temperature and high pressure, and gives some reference to reduce the broken of thin pipes caused by oxidation. This means both theoretical and practical value to the thermal power plant.
