GRAY MODEL AND GRAY RELATION ANALYSIS FOR ATMOSPHERIC CORROSION OF CARBON STEEL AND LOW ALLOY STEEL
碳钢、低合金钢大气腐蚀的灰色模型预测及灰色关联分析

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.
