采用旋转圆筒式冲刷腐蚀装置通过多种电化学测试及失重测量研究了苯并三氮唑（ＢＴＡ） 对ＢＦｅ３０１１ 在单相及含砂人工海水中冲刷腐蚀的抑制作用。结果表明， ＢＴＡ可有效抑制ＢＦｅ３０１１ 在单相及含砂人工海水中冲刷腐蚀的阴、阳极反应， 属几何覆盖型缓蚀剂， 其吸附满足Ｌａｎｇｍｉｕｒ 等温式；ＢＴＡ在单相流动海水中比静态下缓蚀作用更强， 但流速较高时，ＢＴＡ缓蚀作用下降； 在含砂人工海水中， ＢＴＡ 缓蚀作用随砂含量的增加而降低

The corrosion inhibition of BFe3011 in single-phase and sandy artificial seawater by benzotriazole (BTA) was studied by rotating cylinder type erosion and erosion apparatus through various electrochemical tests and weight loss measurements. The results show that BTA can effectively inhibit the anodic and anodic reactions of BFe30-1-1 in single-phase and sandy artificial seawater, which belongs to the geometrically-covered corrosion inhibitor and its adsorption satisfies the Langmiur isotherm. In the single-phase mobile seawater The corrosion inhibition effect of BTA is stronger than that under static condition, but the corrosion inhibition of BTA decreases when the flow rate is high. In sand-containing artificial seawater, the corrosion inhibition of BTA decreases with the increase of sand content
