The surface morphology and transient current response of Fe-16 wt% Cr-16 wt% Ni in a scratch test

This letter deals with a study of the electrochemical behaviour of an Fe-16 wt% Cr-16 wt% Ni alloy, immersed in a 0.01 M H 2 SO 4 -0.01 M KCl solution, when scratched with different hardness indentors. The depassivation characteristics have been studied by relating the transient current response to the different loads applied through the indentors to produce scratches
