| Résumé | In the present studies, efforts were made to improve corrosion resistance of 90CrMoV8 tool steel by following plasma nitriding. Plasma nitriding of this steel at 500 degrees C for 6 and 8 h significantly improved the corrosion resistance when compared to the as-received steel. X-ray diffraction reveals gamma' (Fe, Cr)4 N) and epsilon ((Fe, Cr) 2-3 N) phases formed after nitriding. Potentiodynamic polarization tests in 3.5% NaCl reveal that plasma nitriding significantly improved the corrosion resistance as compared to untreated steel. The improvement in corrosion resistance may be attributed to the N solid solution and the presence of Fe-nitrides formed in the compound layer. (C) 2018 Elsevier Ltd. All rights reserved. |
