Localized corrosion and repassivation behaviors of additively manufactured titanium alloys in simulated biomedical solutions

npj Materials Degradation, 2023
The localized corrosion behavior of additively manufactured (AM) titanium alloys is studied based on the relation between pitting potentials, the flux of oxygen vacancies in a passive film, and the repassivation rate using potentiodynamic polarization ...

Emergence of micro-galvanic corrosion in plastically deformed austenitic stainless steels

Materials & Design, 2021
Localized plastic deformation has been observed to render nuclear reactor components more susceptible to stress corrosion cracking (SCC). However, it is not fully clear how localized strain impacts corrosion (oxidation) behavior.

Three phase corrosion of pipeline steel: Size effects of deposited solids under water droplets and an oil diffusion barrier

Journal of Pipeline Science and Engineering, 2021
Existing studies have examined either under deposit corrosion in bulk solutions or underoil droplet corrosion without deposits. Yet, neither of these scenarios represents the conditions existing within a diluted bitumen pipeline where underoil droplet ...

Electrochemical tomography as a nondestructive technique to study localized corrosion of metals

npj Materials Degradation, 2021
We present an approach, termed electrochemical tomography (ECT), for the in-situ study of corrosion phenomena in general, and for the quantification of the instantaneous rate of localized corrosion in particular.
