Abstract

This article discusses the elements necessary for a galvanic cell operation. Detailed information on the possible corrosion reaction as a function of aqueous electrolyte concentration and pH, in the presence of certain ions, are provided using Pourbaix diagrams. A variety of atmospheric factors, climatic conditions, and air-chemical pollutants that determine the corrosiveness of the atmosphere and contribute to the metal corrosion process are discussed. The article reviews the phenomenon of precipitation runoff on the corroded metal surface and the corrosive microbial effect on metals. It describes the thermodynamics of atmospheric corrosion and models for predicting the corrosion damage of metals. The article concludes with information on the various trends in atmospheric corrosion research and methods for the corrosion processes.
