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30 kV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。

该数据为未添加缓蚀剂钢片扫描电镜形貌。

HITACHI S-4800 field emission scanning electron microscope (SEM) was used to analyze and study the surface condition of N80 steel sheets. After the acid corrosion and not acid corrosion of N80 steel plate were taken by distilled water and organic solvent cleaning, in the accelerating voltage of 30 kV under the electron microscope, under the conditions of magnification 100-3000 times the morphology of the surface of the steel plate scanning characteristics of the observation, comparison of different corrosion specimen surface morphology to compare the corrosion inhibition of different corrosion inhibitors performance advantages and disadvantages.This data is the scanning electron microscope morphology of the steel sheet without corrosion inhibitor.
