Applications of a Novel Wireless System for Real‐Time Atmospheric Corrosion Monitoring

ABSTRACT Real‐time evaluation of atmospheric corrosivity is of high importance for both technical and scientific applications. However, it remains challenging, particularly due to the dynamic nature and variability of the environment. The present study demonstrates cases of use of a state‐of‐the‐art corrosion monitoring system. Two laboratory studies focused on automotive applications were carried out to assess the effect of parking conditions and to investigate the possibility of galvanic coupling between rubber and the metallic car body. Two other studies performed in operating environments assessed factors controlling corrosivity of swimming pool atmospheres and evaluated the design of junction boxes in view of humidity retention and corrosivity towards electrical components. Simultaneous measurements of temperature, relative humidity, and corrosion rate helped to understand the effect of climatic parameters on corrosion behaviour and identify critical scenarios. In all the presented cases, humidity was found to be the dominant factor for corrosion initiation. However, the critical humidity levels inducing maximum corrosion varied considerably depending on the type of pollutant present.
