一、序言过去曾经对钢在海洋环境中的腐蚀情况进行过很多研究工作。但多半是选择无潮流的比较平静的清净海域等特定海域作试验点的。考虑到实际上钢材是在各种海洋环境下使用的,因此有必要查明钢材在各种环境条件下,在不同的海水中的腐蚀行为。从这种观点出发,我们选择了城市工业地区的海湾内,潮流影响显著的海峡,水下30公尺与水下60公尺的海底等四种不同条件的海水环境,进行了钢的腐蚀调查。同时,查明了本公司生产的耐海水钢的特性。
I. Preface In the past, there have been many studies on the corrosion of steel in the marine environment. But most of them choose to test points for specific sea areas such as the relatively calm and clean sea without tidal current. In view of the fact that steels are used in a variety of marine environments, it is necessary to find out the corrosion behavior of steels in different seawater under various environmental conditions. From this point of view, we have selected the seawater environment of four different conditions within the bay of the industrial area of the city, the channel of which the trend is significant, the underwater of 30 meters and the underwater of 60 meters, and the corrosion of steel is investigated . At the same time, the company has identified the characteristics of seawater resistant steel.
