Abstract The potential for crevice corrosion of UNS30400 stainless steel in the presence sulfate-reducing bacteria (SRB) was studied different media. Immersion studies found to occur test media supplemented with high chloride levels and SRB present gaps ~3 μm. Electrochemical measurements showed susceptibility this particular medium, demonstrated by a negative shift open circuit potential, incr...

Titanium tubes generally exhibit superior resistance against electrochemical corrosions amid seawater for their passive films TiO2. However, hydrogenassisted corrosion (HAC) is actually the Achilles’ heel to titaniummaterials when the temperature exceeds near 70 8C. In this event, severe degradations like quick thinning and leakage were frequently detected on a large number of titanium tubes ex...

Corrosion of titanium dental implants has been associated with implant failure and is considered one of the triggering factors for peri-implantitis. This corrosion is concerning, because a large amount of metal ions and debris are generated in this process, the accumulation of which may lead to adverse tissue reactions in vivo. The goal of this study is to investigate the mechanisms for implant...

In the present work, existing Indian elastic rail clip steel (tempered martensite) is microstructurally modified to bainite using austempering route. Crevice corrosion of (ERC) major concern as metal dissolution can cause loosening assembly (such clipinsert and clipliner) lack performance. Furthermore, surface exposed atmosphere could also be affected by corrosive environment. The work concentr...

The mechanism of general corrosion Alloy 690 in simulated steam generator crevices is investigated by voltammetry, electrochemical impedance spectroscopy and slow strain rate tests, combined with ex-situ characterization the oxides using X-ray photoelectron Glow-discharge optical emission spectroscopies. Quantitative interpretation spectra Mixed-Conduction Model furnishes estimates kinetic tran...
