Avaliação do efeito de gases poluentes na corrosão metálica: um experimento para o ensino da corrosão

Abstract

EVALUATION OF THE EFFECT OF GASEOUS POLLUTANTS IN METALLIC CORROSION: AN EXPERIMENT FOR TEACHING OF CORROSION. In this work one proposes a didactic experience to simulate atmospheric corrosion of copper and nickel, due to sulfur dioxide presence. This is an opportunity to understand some basic aspects of atmospheric corrosion, by using fundamental concepts in chemistry, reactions of extraction and characterization of pollutants, as well as their participation in corrosion process. This subject opens a space for discussion about necessity of pollutant gases emissions control for preservation of materials and the environment.
