海水对金属腐蚀因素的分析及预测

Analysis and Forcasting for Main Factors of Corrosion to Metals in Ocean Enviroment

摘要: 应用灰关联分析原理讨论了海水环境与金属腐蚀性之间的关系.基于灰关联度的计算,找出了在全浸带条件下,海水中对A₃钢具有腐蚀影响的主要因素,利用人工神经网络BP算法建立了海水环境对A₃钢的腐蚀作用模型,用该模型预测了新海水域环境下金属的腐蚀速度,取得了较好的结果.

Abstract: The relationships between ocean corrosion of metal and the ocean environment were studied by grey relational analysis methods. Under the submergence, the main factors of corrosion for A₃ steel in ocean environment were found in accordance with grey relation grade. Neural network was applied to set a madel of ocean corrosion to A₃ steel. Then the model is used to predict the corrosion rate of A₃ steel in the new ocean environment and a satisfied result is obtained.
