摘　　要：通过腐蚀失重、扫描电镜和能谱分析等方法，模拟“三顶”冷凝冷却系统腐蚀环境，研究了改性咪唑啉缓蚀剂SD03在金属材料表面的成膜性能以及影响缓蚀剂成膜的因素。结果表明，缓蚀剂SD03的用量在20μg/g以上、pH值为5～7的条件下对碳钢表面形成的保护膜的致密性和均匀性较好，具有很好的缓蚀效果。同时研究发现缓蚀剂SD03在CrSMo材料表面的成膜规律与碳钢相似。The filming performance on metal surface and impact factor of a modified imidazoline corrosion inhibitor SD03 in crude distillation unit overhead corrosion environment were investigated by corrosion weight loss testing, scanning transmission electronic microscopy and energy spectrum. The experimental results indicated that, when concentration of inhibitor SD03 exceeds 20 ppm and the pH is 5 - 7, the filming performance of inhibitor SD03 on the surface of carbon steel is good in uniformity and stability. In addition, the filming performance of inhibitor SD03 on the surface of CrSMo steel has the same characteristic as that carbon steel.
