Název v původním jazyce

Corrosion resistance of plasma nitrided structural steels

Popis výsledku v původním jazyce

This study is focused on evaluation of corrosion resistance of plasma nitrided structural steels under several nitriding conditions. Experiments were performed on structural steels CSN 41 2050 (C45E), CSN 41 4220 (16MnCr5) and CSN 41 5230 (DIN 1.7361). Selected structural steels were manufactured for experimental specimens (size of 80x50x4 mm), heat-treated and plasma nitrided under following conditions: T = 500 °C, process duration t = 10 and 20 h, p = 280 Pa, U = 510 V and variable gas mixture ratio of 3H2:1N2 [l/h] and 1H2:3N2 [l/h] for different compound layer phase composition. Corrosion tests were performed in the Liebisch GmbH & Co (S 400 M-TR) corrosion chamber in the mist of neutral sodium chloride dilution (NSS method), evaluated and documented in accordance to ISO 9227 standard and results compared to different plasma nitriding conditions. Under different plasma nitriding conditions were different nitride layer characteristics obtained. Nitride layers were by surface hardnes
