- Corrosion resistance of nitrogenated high-carbon martensitic stainless steel designed and produced at nitrogen low pressures Pablo Miguel Coha-Vesga Guilherme Yuuki-Koga Martin Emilio Mendoza-Oliveros Francisco Gil-Coury Lais Mujica-Roncery Ingeniería MEV dureza CALPHAD carburo corrosión A new martensitic stainless steel with high nitrogen and carbon content at low pressures was designed using the CALPHAD method. The chemical composition of the steel was checked by optical emission spectrometry, obtaining 0.17 wt%-N and 1.33 wt%-C. Scanning electron microscopy (SEM) analyses were carried out for microstructural characterization. The properties of the steel were assessed by Rockwell hardness and potentiodynamic polarization tests in 0.6M NaCl. The steel showed maximum hardness values of 60 HRC, regarded as a hard material. However, the passive film formation was prevented by the high carbon content promoting excessive Cr-rich carbides. 2023 artículo científico 1657-4583 https://www.redalyc.org/articulo.oa?id=553781606015 https://www.redalyc.org/journal/5537/553781606015/ https://www.redalyc.org/journal/5537/553781606015/html/ https://www.redalyc.org/journal/5537/553781606015/553781606015.epub https://www.redalyc.org/journal/5537/553781606015/movil 10.18273/revuin.v22n4-2023015 en http://www.redalyc.org/revista.oa?id=5537 Revista UIS Ingenierías application/pdf Universidad Industrial de Santander Revista UIS Ingenierías (Colombia) Num.4 Vol.22
