Study on the Corrosion Resistance Mechanism of Nitric Acid Passivation on 316L and SUS329J3L Duplex Stainless Steels in a Denitrification Agent

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Март 13, 2025

316L and DSS 2205 suffer from pitting corrosion in a denitrification agent, NaClO2 solution, despite their excellent resistance widespread utilization plants. Herein, nitric acid passivation was successfully employed to enhance the of 3% solution. The which showed lowest rate, chosen by electrochemically studying effect concentration on steel's series solutions containing 1%, 3%, 6%, 10% NaClO2. passive films with without were investigated chemical composition, electrochemical property, semiconductor behavior, morphology observation analyses. enhanced both after attributed Cr enrichment decreased active area steel surface. property test point defect model that reduced doping density diffusivity contributed better against ClO2– Cl–. passivated according tests potentially is an option replace high-cost 2205.

Exploring the Effect of Lanthanum on the Corrosion Resistance and Antimicrobial Properties of Fe–20Cr–18Ni–6Mo–0.8Cu–0.2N Stainless Steel in Seawater

Advanced Engineering Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 1, 2025

This study investigates the effects of lanthanum (La) on microstructure and corrosion resistance Fe–20Cr–18Ni–6Mo–0.8Cu stainless steel in seawater. Microstructural analysis shows that La addition refines grain size alters precipitated phases. X‐ray diffraction confirms austenitic structures, while transmission electron microscopy reveals formation Cu 5 compounds ferrite/σ Electrochemical tests indicate sample without has highest open‐circuit potential best nonseawater conditions. However, after 16 days seawater exposure, 0.5 wt% exhibits superior with a rate 0.0175 mm/a, higher contents (1.0 1.5 wt%) leads to poor large craters. Scanning minimal surface for sample. In sulfate‐reducing bacteria environments, enhances resistance, except pitting observed Kelvin probe force fluctuation (from −30 10 mV) 0 sample, indicating resistance. provides insights into role rare earth elements super steels.
