Short communicationAssessing atmospheric corrosion of metals by a novel electrochemical sensor combining with a thin insulating net using electrochemical noise technique

•Atmospheric corrosion is monitored by electrochemical noise technique.•A novel electrochemical sensor for electrochemical noise test is designed.•Atmospheric corrosion rate is evaluated by noise resistance.•Atmospheric corrosion form is identified by wavelet analyses.

In this work, a novel electrochemical sensor combining with a thin insulating net is designed for monitoring atmospheric corrosion of metals by using electrochemical noise (EN) technique. Experimental results reveal that the sensor can successfully in-situ detect the atmospheric process and the corresponding corrosion form, which has promising applications in the field of atmospheric corrosion monitoring of metal structures in the future.
