Plasma Nitriding of 90CrMoV8 Tool Steel for the Enhancement of Corrosion Resistance
Article dans une revue avec comité de lecture
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 oC for6and 8 h significantly improved the corrosion resistance when compared to the as-received steel. X-ray diffraction reveals γ′ (Fe, Cr)4 N) and ε ((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
