用电化学阻抗测量和浸泡实验在高压釜中模拟300m(3.0 MPa)深海环境研究Intershield 300 ENA301有机涂层在3.5%NaCl溶液中的失效行为,并与常压环境中涂层的失效行为对比分析.结果表明:压力加速了涂层的破坏,高压和常压环境中涂层的失效行为不同,压力环境中涂层失效表现为起泡,涂层下的金属未发生腐蚀,常压环境中涂层的失效表现为涂层下金属的腐蚀,而涂层未发生起泡.
The failure behavior of Intershield 300 ENA301 organic coating in 3.5% NaCl solution was simulated by electrochemical impedance measurement and immersion test in an autoclave 300 m (3.0 MPa) deep sea environment. The failure behavior of the coating was compared with that of the coating under atmospheric pressure The results show that the pressure accelerates the destruction of the coating, the failure behavior of the coating under high pressure and atmospheric pressure is different, the failure of the coating in the pressure environment is foaming, the corrosion of the metal under the coating does not occur, The failure of the layer is the corrosion of the metal under the coating without foaming of the coating.
