摘要
应用灰色理论中的GM(1,1)灰色模型和灰色关联分析预测了碳钢、低合金钢在青岛、厦门和榆林全浸区的海水腐蚀速率并研究了海水环境对腐蚀速率的影响。模型经后验差检验显示有很好的精度。通过灰色关联分析建立的海水环境和腐蚀速率关联度显示,海水腐蚀的主要影响因素是溶解氧浓度、pH值和平均盐度。
Using gray model and gray relation analysis of gray theory, seawater corrosion of carbon steel and low alloy steels was predicted and analyzed. The posterior error reification showed that the model had very good precision. And the degree of associatiorn between seawater environment and corrosion rate showed that soluble oxygen concentration, pH and average salinity were main influencing factors on seawater corrosion.
