The container of high-level radioactive waste (HLRW) being in deep geological disposal, the backfill material is needed to serve as second defense for HLRW and highly compacted bentonite generally selected. As time goes, underground water will infiltrate backfill, causing corrosion materials building containers formed electrolyte. Carbon steel, titanium its alloy are potential candidate fabrication containers. current investigation aims at assessing safety disposal hundreds thousands years...
Abstract As a nondestructive and sensitive method, electrochemical impedance spectroscopy (EIS) can be used to investigate the passivation breakdown of passive films on steel. In this study, EIS, combined with slow strain rate test scanning electron microscopy, was employed study stress corrosion cracking (SCC) behavior 2205 duplex stainless steel in 0.5 m sulfuric acid solution under hydrogen-charging conditions. Results showed that resistance film hydrogen-charged specimen lower than for...
Immersion experiment was used to elucidate the corrosion mechanism of low‐alloy pipeline steel exposed vapor‐saturated H 2 S/CO and ‐saturated brine conditions in terms microstructure, kinetics, products, surface/cross‐sectional morphology, elemental distribution. The experimental results demonstrate that microstructure designed is tempered martensite, rate condition larger than condition. main product two FeS, which shows various crystal structures. size products formed smaller condition,...
In this work, the characteristics of passive films formed on as-cast Ti-6Al-4V before and after transpassivation by electrochemical methods will be studied. A simulated body fluid Hank’s solution was used as electrolyte in work. According to potentiodynamic polarization test, passivation range, transpassive repassivation range were obtained. Afterward, potentiostatic employed passivate both ranges. Electrochemical impedance spectroscopy (EIS) analyze films. Different behavior Ti–6Al-4V is...
Stress corrosion cracking and Hydrogen permeation behavior of X56 grade pipeline steel in simulated atmospheric environment containing SO2 was investigated. The results show that, 1) current can be divided into 3 parts SO2. mainly hydrogen resource is different according to the reaction mechanism. 2) surface ions concentration decrease with time. And this indicates that formation rust. 3) Slow strain rate test (SSRT) shows SCC sensitivity increase due passivation film dissolves increasing.
Purpose Duplex stainless steel is composed of equal amounts austenite and ferrite, which has excellent corrosion resistance strength. However, after the metal was welded, ratio ferrite in joint unbalanced, secondary phase precipitates are produced, also an important cause pitting joint. Design/methodology/approach This paper aims to study mechanical behavior welded joints, by adjusting welding parameters laser hybrid welding, dual heat sources used weld 2205 duplex steel. The two-phase...
In this work, the corrosion behavior of copper in a simulated organic acid environment containing formic and acetic was investigated by electrochemical testing surface characterization. addition to deducing mechanism environment, inhibitor BTA also used slow down acid. The results show that rate two groups acids first decreases then increases with immersion time. Microelectrochemical (Scanning Vibrating Electrode Technique) shows anodic peak sample is higher Formic more corrosive. products...
Purpose This paper aims to study the effect of current density hydrogen charging on semiconductor properties and pitting initiation 2205 duplex stainless steel (DSS) passivation film. Design/methodology/approach In this work, DSS is pre-hydrogenated passivated. Then, film tested by electrochemical impedance method, Mott–Schottky curve method dynamic potential scanning method. The influences corrosion behavior matrix were studied analyzing curves obtained in test. surface after...
