摘要
对产生腐蚀隔热管接箍进行了化学成分、金相组织、腐蚀产物的X射线衍射和能谱检查与分析,找出了隔热管接箍产生腐蚀的原因。
The macroscopic, the chemical composition ,the metallographic structure,the Xray diffraction diagram and spectrography of the corroded tube couplings and corrosion products(residue) have been analyzed to ascertain the reasons for the occurrence of severe corrosion.
