Abstract: |
By means of macroscopic observation, chemical composition analysis, microstructure observation and scanning electron microscopy, the corrosion causes of the inner chamber of the attitude control engine in Qinling Mountains mountain area were analyzed. The results show that the corrosion of the inner chamber of the engine is caused by electrochemical corrosion, and is related to the special environment of Qinling Mountains mountain area. |
