摘要

防海生物污损药剂在海洋工程及舰船领域的应用,不仅要考虑防污效果的有效性,还要评价其对工程结构材料腐蚀安全性的影响。针对即将应用于舰船通海结构防海生物污损的某药剂,研究其加入后对TA24钛合金及907A合金钢2种具有代表性的舰船金属结构材料在海水环境中腐蚀行为和速率的影响。经过腐蚀形貌、失重率、开路电位、极化曲线、交流阻抗等综合分析和评估,该药剂对这2种材料腐蚀行为影响较小,不会产生明显腐蚀加速。

Abstract

To apply anti-marine biofouling agents in the fields of marine engineering and ships, not only the antifouling effectiveness, but also their impact on the corrosion safety of engineering structural materials should be seriously considered and evaluated. Effects of the addition of an agent that would be applied to the anti-marine biofouling of the ship’s sea-access structure on the corrosion behavior and rate of two representative ship metal structural materials, TA24 titanium alloy and 907A alloy steel, in seawater environment were studied. From the comprehensive analysis and evaluation of corrosion morphology, weight loss rate, open circuit potential, polarization curve and alternating-current impedance, it could be obtained that the agent had little effect on the corrosion behavior of these two materials and would not accelerate the corrosion significantly.

Key words： marine biofouling; corrosion; titanium alloy; alloy steel
