| 中文摘要: |
| 通过失重法测定腐蚀速率,并计算缓蚀率,确定了具有较好协同缓蚀效应的四元无磷海水缓蚀剂配方,并通过电化学极化、SEM、 EDS 等分析手段,对该无磷海水复合缓蚀剂的缓蚀机理进行了研究。 结果表明:配方以 40 mg / L 钨酸盐+40 mg / L 葡萄糖酸盐+4 mg / L Zn2++30 mg / L 三乙醇胺为宜,该缓蚀剂在海水中对碳钢的缓蚀率超过 90% ;此无磷复合缓蚀剂为阳极型缓蚀剂,海水中添加了此缓蚀剂后,碳钢试片表面形成了以氧化铁为主要成分,同时含有钨和锌的混合型沉淀膜。 |
| 英文摘要: |
| A quaternary corrosion inhibitor formula without phosphorus, which has a good synergistic effect was conformed in natural seawater through measuring corrosion rate and corrosion rate with the weight loss method. Corrosion mechanism of the compound corrosion inhibitors was studied through the electrochemical polarization, SEM and EDS analysis method. The results indicate that the inhibition efficiency is over 90 % in the proportion of 40 mg / L stungstate,40 mg / L sodium gluconate,4 mg / L Zn2+and 30 mg / L TEA. The compound inhibitor is an anodic corrosion inhibitor which formes a compact film on carbon steel surface, the main composition of the film is iron oxide with some W and Zn. |
