The roles of the alloying elements Mo, Cr, and W in resisting crevice corrosion of UNS N06022, UNS N06625, and UNS N10362 have been studied under galvanostatic conditions in 5 mol/L NaCl at 150°C. Corrosion damage patterns were investigated using surface analytical techniques such as scanning electron microscopy and optical imaging, and the corrosion products characterized by energy dispersive x-ray spectroscopy. While the Cr content of the alloy is critical in controlling initiation of crevice ...

Abstract The effects of γ-radiation on the corrosion of a cobalt-based alloy, Stellite-6, were studied at pH 6.0, 8.4 and 10.6 at room temperature. The type and thickness of the oxide formed and the dissolved cobalt content were analyzed following 3-d long corrosion tests using coupons in sealed vials. Oxidation kinetics were studied by monitoring the corrosion potential as a function of test conditions and by performing potentiostatic polarization tests as a function of applied potential. The r...

Hydrogen (deuterium) absorption into sputter-coated titanium (Ti) film electrodes during cathodic polarization in heavy water (D2O) was monitored using in-situ neutron reflectometry (NR) and electrochemical impedance spectroscopy (EIS). The scattering length density (SLD) of Ti metal increased with increasing cathodic polarization, due to the penetration of deuterium through the surface oxide and into the underlying metal. The rate of D absorption estimated from the NR data showed a pattern with...

Severe corrosion damage may occur when gas transmission pipelines are exposed, at disbonded coating locations, to trapped waters containing sulfide. This scenario has been investigated in long-term anaerobic experiments in which corrosion was followed by measurement of corrosion potentials and relative corrosion rates obtained from linear polarization resistance measurements. The properties and composition of the corrosion product deposits formed were determined using scanning electron microscop...

Abstract Gamma-irradiation significantly increases the corrosion potential on pure Co and the cobalt alloy, Stellite-6. To understand the radiation-induced corrosion of these materials, electrochemical studies of film formation and conversion on these metals were performed as a function of potential under both potentiodynamic and potentiostatic conditions. The oxidized surfaces were characterized by electrochemical impedance spectroscopy and X-ray photoelectron spectroscopy. Four characteristic ...

Abstract Crevice corrosion of alloy-22 was studied galvanostatically (10–200 μA) at 120 °C in 5 M NaCl. Corrosion damage was analyzed by confocal laser scanning microscopy to obtain penetration profiles. Three-dimensional images demonstrate that damage morphologies varied with applied current. At low applied currents (⩽70 μA), propagation predominantly leads to penetration into the alloy, whereas at higher applied currents (>70 μA) corrosion damage spreads across the alloy. Limited penetration d...

Abstract The initiation and propagation of crevice corrosion on the Ni–Cr–Mo Alloy-22 has been studied in concentrated chloride solutions under galvanically-coupled and galvanostatic conditions. Under galvanically-coupled natural corrosion conditions crevice corrosion initiated but propagation was limited by repassivation. This was attributed to the slow kinetics of oxygen reduction on passive surfaces external to the crevice. Under galvanostatic conditions a potential more positive than 200 mV ...

Abstract The reaction kinetics of AgI formation by reaction of Ag 2 O films with aqueous iodide were followed by monitoring the open-circuit potential ( E OC ). Previous studies have shown that complete conversion of Ag 2 O to AgI is indicated by an abrupt transition in the E OC from a value close to the equilibrium potential for the Ag|Ag 2 O|H 2 O system to one close to that for Ag|AgI|I − , allowing an easy determination of the total reaction time, τ f . The solid–solution interfacial kinetic...
