This work shows the results of this process through the realization of a duplex treatment that combines the application a single chromium hard coating Cr(VI) on a steel AISI H13 with a thermochemical treatment of gaseous vacuum nitriding. The electroplated coating thickness was 15 μm, and N2 was used as precursor gas, with a flow of 100 ml/min at a pressure of 1,2 kPa. The existing phases were determined by means of X-ray diffraction, and the corrosion resistance was evaluated by potentiodynamic polarization and electrochemical impedance spectroscopy techniques in a three electrode electrochemical cell. The characterization by XRD could determine the presence of chromium nitrides of type Cr2N, with an important orientation in the plane (300) associated with the partial pressure of N2 and the thermodynamic behavior. The corrosion resistance results showed a significant decrease in the corrosion current density compared to those exhibited by samples electroplatedally chromed with steel AISI H13 without nitriding. These results, coupled with the sealing of characteristic microcracks of the electroplated chrome coating, could improve the corrosion resistance, because of the existence of the CrxNy phase.
