Applications of Electrochemical Potentiokinetic Reactivation Test to On-Site Measurements on Stainless Steels


The aim of the paper is to present some applications of the Electrochemical Potentiokinetic Reactivation (EPR) technique to the characterization of the corrosion resistance of stainless steels apparatus.

In particular, the use of the technique to the detection of chromium depletions on insufficiently pickled austenitic steels is explained. The application of the method to determine the degree of sensitization of duplex stainless steels by intermetallic phase precipitations is also discussed.

Then, the paper presents the possibility of use of the EPR test for on-site measurements, with a portable equipment.
