| 摘 要： | 采用极化曲线、交流阻抗、溶液分析等方法研究了苯并三氮唑(BTA)与碘化钾(KI)对天然海水中黄铜的协同缓蚀作用及加药顺序对缓蚀性能的影响.结果表明,当BTA和KI的使用浓度分别为2 mg/L和10 mg/L时,对黄铜的缓蚀率达到97.19%;考虑加药顺序后缓蚀率可进一步提高到99.31%.极化曲线测试表明,BTA与KI复配为混合型缓蚀剂,且抑制阴极反应的程度更强.SEM照片显示,添加了BTA与KI缓蚀剂的铜片表面基本没有腐蚀.溶液分析显示添加了BTA与KI复配缓蚀剂后有效地抑制了黄铜的脱锌腐蚀.

| Abstract: | The synergistic effect between benzotriazole(BTA) and KI on the corrosion inhibition of brass in seawater has been studied using electrochemical polarization,EIS,weight loss,solution analysis,and SEM methods.The results indicated that there was a good synergistic effect between BTA and KI.While the concentration of BTA and KI were 2 mg L-1 and 10 mg L-1,respectively,the inhibition efficiency reached 97.19%.The maximum inhibition efficiency even reached 99.31% considering the adding order of inhibitors.Polar... |
