The Effect of Plasma Nitriding on the Corrosion Resistance of Martensitic Stainless Steel X12Cr13

Original language description

The plasma nitriding technology was applied on the martensitic stainless steel X12Cr13. The influence of plasma nitriding on the corrosion resistance of selected material was investigated. The chemical composition of selected steel was verified using the Q4 TASMAN device. The plasma nitriding process was performed using two stage nitriding procedure. After plasma cleaning procedure at 515 °C for 45 min in nitriding atmosphere ratio 20H2:2N2 (l/h) was the first stage nitriding procedure performed at 520°C for 16 hours in nitriding atmosphere ratio 25H2:5N2 (l/h) and followed by second stage of nitriding procedure performed at 525°C for 4 hours in nitriding atmosphere ratio 28H2:4N2 (l/h). The microstructure and mechanical properties of the nitride layers were studied using the OES spectrometry, optical microscopy, and hardness testing. The depths of plasma nitride layers were also estimated using cross-sectional microhardness profiles measuring. The corrosion resistance testing of plasma nitrided stainless steel X12Cr13 samples were carried out in a 5 % neutral sodium chloride solution (NSS) in accordance with ISO 9227 standard in the VLM GmbH SAL 400-FL corrosion chamber and visually evaluated. Microhardness and surface hardness of experimental samples were significantly increased, but the corrosion resistance significantly decreased.
