Improvement Of The Corrosion Resistance Of The Stainless Steel With The Plasma Nitridingand The Chemical Polishing As Two Different Mechanisms
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Two different techniques have been studied to improve the corrosion resistance of the austenitic stainless steel(304L). The first technique is the plasma nitriding using a mixture of N2-H2 gasesand the second technique is the chemical polishing. The potentiodynamic polarization measurements were used to compare between the effects of the two techniques on the corrosion resistance of the stainless steel. The corrosion potential of thenitrided sampleswas improved by 61% while in the case of the samples that chemically polished it was improved by 13%. X- ray diffraction (XRD) pattern of the nitride sample confirms the formation of Fe2-3N, Fe4N, and CrN nitridephases and also the formation of the super saturated nitrogen-rich phase "S-phase" which has important role in the improvement of the corrosion resistance. The surface morphology of the two samples confirms the formation of the S- Phase. The grain size of the nitride sample was about 50.25 nm.
