The present work describes the corrosion studies (using electrochemical techniques) of coated
and uncoated steels exposed to corrosive mixtures (including 6% ferric Chloride, alcohols, particles
and water). Open Circuit Potential (OCP), Cyclic Potentiodynamic Polarization (CPP) and a modified
version of the Zero Resistance Amperometry (ZRA) testing methodology were proposed to compare
the corrosion resistance of several steel exposed to these environments.
The modified version of the ZRA is not only measured accurately (within 1oC) the Critical Pitting
Temperature (CPT) on the different alloys studied (metallic bars exposed to 6% Ferric Chloride), but
also allowed to perform the testing in a very short time. This technique is a promising way to
characterize and rank different materials subjected to the same environmental conditions.
