Abstract

Polyanisidine (POA) and polyanisidine-molybdate (POA−MoO42-) coatings have been successfully synthesized on steel grade СТ3 from aqueous solutions of oxalic acid by electrochemical method using cyclic voltammetry. The morphology and composition of these films were characterized by scanning electron microscopy (SEM) and energydispersive X-ray (EDAX) methods. It was proven that the introduction of MoO42- into the polyanisidine matrix raised the corrosion resistance of the POA coating and also improved its adhesion properties. The protective properties of steel grade CT3 with POA and POA-MoO42- films were studied using potentiodynamic polarization in 3.5% NaCl solution. The results showed that ions improve anti-corrosion properties of POA films.

POA−MoO42-涂层在3.5% NaCl中的电化学合成、表征及腐蚀性能

以草酸水溶液为原料，采用循环伏安法在СТ3钢表面成功合成了聚乳酸菌胺（POA）和聚钼酸乳酸菌胺涂层。用扫描电子显微镜（SEM）和能量分散X射线（EDAX）方法对这些薄膜的形貌和组成进行了表征。研究表明，在聚乳酸菌胺基体中引入MoO42-，不仅提高了POA涂层的耐腐蚀性，而且提高了涂层的附着力。在3.5%NaCl溶液中，采用动电位极化法研究了POA和POA-MoO42-膜对钢级CT3的保护性能。结果表明，离子能提高POA薄膜的防腐性能。
