Abstract

Atmospheric corrosion commonly initiates and develops under thin water films formed by dew or rain drops. A composition of water film depends on the air pollutant deposition rate, and changes with the humidity and temperature conditions of the atmosphere. Many sensors and the measurement techniques have been developed to evaluated corrosivities in atmospheric environments and corrosion behaviors in those environments. In this paper, the present state and visions of atmospheric corrosion researches are discussed based on the roles of water and deposits and environmental factors which are evaluated by those sensors and measurement techniques.
