摘要
应用灰关联分析方法解析海水环境因素与海水腐蚀性的关系。根据灰关联度的计算 ,在诸海水环境因素中找出影响碳钢和低合金钢在海水中局部腐蚀深度的主要影响因素 ,指出了各因素对钢局部腐蚀的影响程度。文中还提出海水腐蚀性评价因子 。
The relationships between corrosion of steels and environmental factors in sea water have been studied by grey relational analysis method.The main factors influencing localized corrosion depth of carbon steels and low alloy steels in sea water were found in accordance with grey relational grade and these dependence degree were also evaluated.The most important 3 environmental factors for marine corrosion of these steels included seawater tempenature, adhesion area of marine animals and plants and pH. Meanwhile the evaluation factor for seawater corrosivity Q=3i=1(Y i×f i) was proposed. Here Y i refers to the above mentioned 3 environmental factors, and f i is the grey relational grade of these factors to localized corrosion depth.
