Corrosion Resistance of High Temperature Plasma Nitrided X12CrMoWVNbN10-1-1 Martensitic Stainless Steel
Original language description
The X12CrMoWVNbN10-1-1 martensitic stainless steel was subjected to plasma nitriding at an increased temperature of 550 degrees C for 15 h and compared to untreated one. The microstructure and microhardness of the untreated and nitrided stainless steel were evaluated. The corrosion properties of the untreated and plasma nitrided steel samples were evaluated using the anodic potentiodynamic polarization tests in neutral 2.5% NaCl deaerated solution. The results showed that plasma nitriding process on the X12CrMoWVNbN10-1-1 stainless steel produced a nitride layer consisting of compound layer and a nitrogen rich diffusion layer. Plasma nitriding process significantly increased the surface hardness of the martensitic stainless steel but also decreased the corrosion resistance of the X12CrMoWVNbN10-1-1 stainless steel. The pitting was evaluated, and the pitting coefficient was calculated. During electrochemical corrosion tests, the nitrided steel showed lower (more negative) corrosion potentials, higher current densities and greatly increased corrosion rates and pitting.
