Atmospheric Corrosion Dose/Response Functions from Statistical Data Analysis for Different Sites of Mexico

This work presents the dose/response functions from linear regression analysis of atmospheric corrosion statistical data from different sites of Mexico. During the last fifteen years atmospheric corrosion characterization was obtained from different sites, and the results were used as a database for statistical analysis and linear regression modelling, obtaining the Atmospheric Corrosion Dose/Response Functions presented here. The contribution of each relevant environment variable for steel, zinc, copper and aluminium atmospheric corrosion, were obtained. The models present good regression, correlation coefficients, depending on the variables considered in the analysis. Also, using experimental data, an example is presented for modelling and obtaining atmospheric corrosion iso-linear maps for different materials in the municipal area of the city of Cuernavaca, Morelos; Mexico for the prediction of atmospheric corrosiveness of sites with unavailable experimental data.
