Prediction of first-year corrosion losses of copper and aluminum in continental regions

The dose-response functions (DRFs) developed for the prediction of first-year corrosion losses of copper and aluminum ( K 1 ) in continental regions are presented. The development of DRFs is based on the stablished dependences of the corrosion losses of these metals on SO 2 concentration: K = f ([SO 2 ]). Experimental data on the atmosphere corrosivity and corrosion losses of the metals in a one-year exposure period according to ISOCORRAG and UN/ECE international programs, the Russian program, and МICAT project were used. Comparisons of the predicted K 1 values obtained by three different DRFs with experimental K 1 values are presented. These DRFs are analyzed in terms of the coefficients they contain.
