摘要: 

对赤道高温海域及极地低温海域与我国近海海域的海水温度、盐度、溶解氧含量和pH值等与材料腐蚀强相关的环境因素规律特征进行了对比分析,结合T2铜合金的腐蚀速率数据以及海水环境因素数据,采用灰关联分析方法对极端海域及我国近海海域的海水腐蚀性进行了计算,基于计算结果对极端海域海水腐蚀性进行了对比研究,结果表明,对T2铜合金来说,赤道高温海域海水腐蚀性最强,温度是主要影响因素。

Abstract

The ordinary characteristics of important environmental factors, including seawater temperature, salinity, dissolved oxygen content, and pH value, which are strongly associated with material corrosion in equatorial high-temperature sea areas, polar low-temperature sea areas, and China's coastal sea areas, were systematically compared and analyzed. Based on the corrosion rate data of T2 Cu-alloy and the relevant environmental parameters of seawater, the corrosivity of extreme marine environments and those along the coastal regions of China was assessed using the grey correlation analysis method. Based on the calculated results, a comprehensively comparative study on the corrosivity of seawater in extreme marine environments was performed. The results indicated that among others, the seawater in tropical high-temperature regions exhibited the highest corrosivity, while temperature being the predominant influencing factor.
