摘要
用失重法和电化学法研究了稀土钇 (Ⅲ )离子和非离子表面活性剂聚乙二醇辛基苯基醚 (OP)在磷酸介质中对锌腐蚀速度的影响 ,发现在特定浓度范围内 ,钇离子和OP对锌有强烈的缓蚀协同作用 。
The effect of Y (Ⅲ) ion and non ionic surfactant polyethlene glycol mono (P) octyl phenyl ether (OP) on corrosion rate of zinc in phosphoric acid solution has been investigated using the weight loss and electrochemistry methods. It was found that a powerful corrosin inhibition synergism for zinc appeared at a special concentration range of Y (Ⅲ) ion and OP. The mechanism of corrosion inhibtion synergism has been discussed with adsorptioin theory on metal surface.
