PREDICTION OF STEEL ATMOSPHERIC CORROSION BY MEANS OF ARTIFICIAL INTELLIGENCE METHODS

Atmospheric corrosion of metal materials exposed under atmospheric conditions depends on various factors such as local temperature, relative humidity, amount of precipitation, pH of rainfall, concentration of main pollutants and exposition time. As these factors are very complex, exact relation for mathematical description of atmospheric corrosion of various metals are not known so far. Classical analytical and mathematical functions are of limited use to describe this type of strongly non-linear system depending on various meteorological-chemical factors and interaction between them and on material parameters. Nowadays there is certain chance to predict a corrosion loss of materials by artificial intelligence methods. The contribution deals with the use of artificial neural networks for prediction of steel atmospheric corrosion.
