中文摘要:
      进行T2/TC4电偶对在静态人造海水中的电偶腐蚀实验,通过电化学工作站、原子发射光谱分析仪、扫描电子显微镜(SEM)、能谱仪(EDS)、X射线衍射仪(XRD)研究T2/TC4在静态人造海水中电偶腐蚀时的铜离子释放速率与腐蚀行为。结果表明:当T2/TC4发生电偶腐蚀时反应强烈,T2为电偶对阳极发生加速腐蚀,TC4为电偶对阴极;与T2自腐蚀相比,T2/TC4电偶腐蚀的铜离子释放速率提高了数十倍,可以维持在160μg/(cm2.d)左右,能达到抑制大多数海洋生物附着的海洋防污要求;T2自腐蚀的腐蚀产物以Cu2O为主,与TC4电偶腐蚀后的T2试样表面无腐蚀产物覆盖。

英文关键词:T2/TC4 galvanic couple  galvanic corrosion  the dissolution rate of copper ion  marine antifouling
英文摘要:
      In this article, galavanic corrosion test of T2/TC4 galvanic couple in static artificial seawater was carried out. The dissolution rate of copper ion and the behaviors of T2/TC4 galvanic couple in static artificial seawater was analyzed by electrochemical workstation, ICP, SEM, EDS and XRD. The results shows that the reaction is intensively when galvanic corrosion occurs between T2 alloy and TC4 alloy, T2 alloy acts as anode and the corrosion rate is increase, TC4 alloy acts as cathode. Compared with the corrosion of T2 alloy, the dissolution rate of copper ion by T2/TC4 galvanic corrosion has been enhanced several times and maintained at around 160μg/(cm2.d), Therefore marine antifouling requirements for inhibiting the attachment of great majority can be achieved. The corrosion product is mainly cuprous oxide when corrosion occurs in T2 sample, No corrosion products are covered on the surface of T2 sample after galvanic corrosion with TC4 alloy.
