采用HITACHI S-4800型场发射扫描电子显微镜（SEM）对N80钢片的表面状况进行分析研究。分别取经酸液腐蚀后的与未受酸液腐蚀的N80钢片经蒸馏水和有机溶剂清洁后，在加速电压为30kV的电子显微镜下，在放大100-3000倍的条件下对钢片表面的形态特征进行扫描观察，对比不同腐蚀试片的表面形态比较不同缓蚀剂缓蚀性能的优劣。

该数据为添加0.3%苯乙基吲哚嗪取代衍生物的扫描电镜形貌数据，共同属于苯乙基吲哚嗪取代衍生物的扫描电镜形貌数据组。

The surface condition of N80 steel sheet was analyzed by HITACHI S-4800 mode field emission scanning electron microscope (SEM). After cleaning the N80 steel sheet with and without acid corrosion by distilled water and organic solvent, the surface morphology characteristics of the steel sheet were scanned and observed under the electron microscope with an acceleration voltage of 30kV and magnification of 100-3000 times, and the surface morphology of different corrosion test pieces was compared to compare the corrosion inhibition performance of different corrosion inhibitors.

This data is the SEM morphology data with the addition of 0.3% phenethylindolizine-substituted derivatives, which together belong to the SEM morphology data set of phenethylindolizine-substituted derivatives.
