摘要
用灰色模型GM(1,1)对碳钢、低合金钢的大气腐蚀速率建立了预测模型,结果显示,该模型具有较高的精度,同时用灰色关联分析方法研究了环境因素对大气腐蚀影响的程度,表明RH>80%的年时数、相对湿度RH、温度是影响大气腐蚀的主要因素.
Atmospheric corrosion rate of carbon steel and low alloy steel was modeled by gray model, the model has very good precision. By using gray relation analysis, the relation between environmental factors and corrosion rate was examined, the result shows that relative humidity, the time of relative humidity〉80 % and temperature are the main influence factors for atmospheric corrosion of carbon-and low alloy-steels.
