Sažetak
In this paper, the influence of water and the influence of the commercial inhibitor VCI 379/611 on the corrosion processes of X153CrMoV12 tool steel for cold work were investigated. The research was carried out by electrochemical methods: by measuring the potential of an open circuit, by determining the corrosion parameters using the method of electrochemical impedance spectroscopy (EIS) and method of Tafel extrapolation. After each measurement, the sample surface was analyzed using an optical microscope. The obtained corrosion parameters showed a high efficiency of the applied inhibitor in the protection of tool steels for cold work from corrosion. For the sample that was exposed to distilled water medium with the addition of inhibitor, a significantly lower corrosion rate was registered and no damage to the sample surface was visible. Metallographic images of the electrode surface after polarization measurements in tap water indicate the occurrence of pitting corrosion.
