Effects of Seasonal Conditions and the Slope of a Specimen on the Atmospheric Corrosion of Steel in the Tropics of Viet-Nam

The results of the field tests of a plain carbon steel in the rural and marine atmospheres of the Northern Vietnam are discussed. The steel specimens were exposed in various year seasons at slope angles of 30° and 45° to the horizontal. The meteorological and aerochemical parameters of enviroment we...

Description
Summary:The results of the field tests of a plain carbon steel in the rural and marine atmospheres of the Northern Vietnam are discussed. The steel specimens were exposed in various year seasons at slope angles of 30° and 45° to the horizontal. The meteorological and aerochemical parameters of enviroment were simultaneously recorded. The effect of the slope angle was noticeable at early stages of the corrosion of a specimen. On the completion of a year-long climatic cycle, the difference in the corrosion effects on the specimens with both the above slope angles did not exceed 10%. During the winter season, the corrosion of the steel is determined by an increased integral time of wetness, TOW (that is, the life time of the films of a corrosive electrolyte at the metal surface).[PUBLICATION ABSTRACT]
