摘要
海底沉积物(以下简称SBS)腐蚀性的评价对海底设施的防腐设计和预防海底设施灾害性的腐蚀具有十分重要的意义。SBS系特殊条件下存在的土壤,因而借助土壤腐蚀性评价法的思路研究SBS的腐蚀性是一捷径。
Weight-loss tests of three kinds of steel were conducted in various sea-bottom sediments. After analysis of sea-bottom sediment investigations results and of data on regional corrosion factors the authors propose a two-factor method for evaluating sea-bottom sediment corrosion. Two main factors affecting corrosion are sediment type and the number of sulfuric reduction bacteria. If A° is corrosion related to sediment type,B° the corrosion related to sulfuric reduction bacteria, then the total corrosion can be expressed as C°= A°+B°.
