Popis:	A method to quantify the degree of sensitization on selective corrosion behaviour is the electrochemical potentiokinetic reactivation method (EPR-Method). Due to the potentiokinetic character, however, the application of the EPR-testing method leads to some difficulties. The corrosion is influenced by kinetic effects and electrolytic secondary reactions and shows a huge dependence on time. Therefore a steady state electrochemical reactivation method to quantify the degree of sensitization on selective corrosion behaviour would lead to a reduction of the mentioned problems and the interpretation, comparability and reproducibility of the achieved results would be more simple and clear. This paper presents the first measurements and results which point to a suitable and promising steady state electrochemical testing method.
