Description
A compact and autonomous corrosion sensor using the principle of electrical resistance variations of its metallic sensitive tracks has been used for different applications under atmospheric corrosion conditions. The measurements of the corrosion rate can be performed in-situ both under laboratory and field exposures. From the results, it is possible to better understand the atmospheric corrosion of zinc and hot dip galvanised steel under various exposure conditions. The technique should also allow the design of reliable and realistic corrosion tests for different industrial applications. From the results it is also shown that the sensor can be a good tool for insitu evaluation of red rust occurrence of zinc coated steel.
