Abstract
This report develops a model for predicting the corrosion of galvanized steel structures based on two competing mechanisms: the formation and dissolution of the basic zinc-carbonate film that forms on zinc surfaces. The model consists of a diffusivity term that describes film growth and a dissolution term that describes the rate of film removal. The field data used in this evaluation were consistent with corrosion rates predicted by the model, within the limits of uncertainty of the environmental data.
