The paper reports the results of simultaneous mechanical and electrochemical investigations on austenitic (18/8) stainless steel in a 2 % solution of sulphuric acid. The measurements were performed using Galvanodynamic Electrochemical Impedance Spectroscopy (GDEIS). Electrochemical analysis of mechanical passive layer cracking and repassivation conditions during a tensile test was carried out. Application of this methodology allowed monitoring of the natural corrosion process without external current (IDC = 0A) nor potential perturbation of the system. The results proved the usefulness of measurements of actual electrochemical systems at zero external current conditions. It was found that a transition to an active state occurred for relatively high strain rates, while the passive layer cracking process did not depend on the strain rate.
