Description
This research tests the corrosion resistance of weathering steel against carbon
steel exposed to dry and humid cycles during laboratory experiments. Various
environments are tested and include the following parameters: chloride
concentration, pH and wetting time. Corrosion values from weight loss analysis are
given and studied for the same environments. X-ray diffraction characterized the
formation of different oxides as a function of the environment and gave a better
understanding on the formation of the protective patina on the weathering steel, and
validated that chamber experiments reproduce field conditions. The study is
supported by the design, test and validation of an easily deployable galvanic
atmospheric corrosion sensor that allowed the monitoring of the corrosion rate on
an hourly basis.
