Abstract

Aerosol salinity and atmospheric corrosion rate of carbon steel were determined at six sites in Nhatrang coastal city. The sites have been selected with different distances from the sea and various heights above sea levels. Results show that the aerosol salinity was strongly influenced by salt collecting positions and by various meteorological parameters, especially by wind speed and directions. Corrosion rates of carbon steel were dependent with the aerosol salinity values at all exposure sites. Besides, atmospheric corrosivities for above mentioned sites of Nhatrang city have been classified according to ISO 9223:1992. Nhatrang atmosphere is considered to be in S1 class by aerosol salinity and C3 class by corrosion rate of carbon steel after first year exposure test.
