摘要/Abstract

摘要： 于实验室模拟深海压力环境,应用电化学阻抗谱(EIS)研究了有机涂料/基底金属的腐蚀电化学行为.分析海水压力对水在涂层中传输行为和涂层防护性能的影响.结果表明,与常压海水相比,在高压海水(3.5MPa)条件下,该涂层具有不同的电化学阻抗特征,主要表现在高压海水加快了涂层的吸水过程,增大了涂层的吸水率,从而加速了涂层的腐蚀失效过程,致使防护性能变差.

关键词: 深海, 压力, 有机涂料, 基底金属, 腐蚀电化学行为

Abstract: By means of electrochemical impedance spectroscopy(EIS),the electrochemical behaviors of organic coating/metal substrate were studied under simulated deep sea environment in the laboratory.Effects of seawater pressure on the transportation behavior of water through coating and the protective performance of coating were analyzed.The experimental results showed that,compared to normal pressured seawater,there were different impedance characteristics of coating in 3.5 MPa pressured seawater.The main observations were that high seawater pressure accelerated the process of water uptake and invalidation of coating,increased water absorption,and lowered the anti-corrosion property of coating.

Key words: deep sea, organic coating, substrate metal, electrochemical behavior
