Investigation of the Atmospheric Corrosion in the Factory Site of a Littoral Industrial Complex Using Carbon Steel Adhesive-backed Test Coupons

Abstract

The atmosphere corrosion tendency across a factory site in a littoral industrial complex was investigated using the carbon steel adhesive-backed test coupons. 150 test coupons of carbon steel were placed in the researched factory site and exposed to the atmosphere for a year. There was a tendency that the corrosion rate of the test coupons decreased with the logarithm of distances from the coastline. The corrosion of the test coupons was accelerated at the places of the high humidity such as around cooling towers. It is thought that the atmospheric corrosion test with the adhesive-backed test coupons is effective as technique to evaluate the tendency of an environmental corrosiveness in factory sites.
