Sensing Atmospheric Corrosion of Carbon Steel and Low-Alloy Steel Using the Electrochemical Noise Technique: Effects of Weather Conditions

Three electrochemical probes were designed to study the effects of weather on the atmospheric corrosion of carbon steel and low-alloy steel in an urban atmosphere by using the electrochemical noise (EN) technique. The fabricated probes can be successfully applied to investigate instant atmospheric corrosion resistance in various weather conditions. Continuous 15-day EN monitoring showed that, under the same weather conditions, the corrosion resistance of Q235 carbon steel is higher than that of low-alloy steels.
