Insight into TiN inclusion induced pit corrosion of interstitial free steel exposed to aerated NaCl solution

open access: yesJournal of Materials Research and Technology, 2021
The mechanism of step-like corrosion pit induced by TiN inclusion in Ti-stabilized interstitial free steel was systematically investigated. There was neither micro-crevice nor local stress in the steel matrix adjacent to the TiN inclusion, but a ...

Research on Evaluation Methods of Material Pitting Corrosion Based on Modal Analysis [PDF]

open access: yesCailiao Baohu, 2022
Pitting corrosion destroys the continuity of the material structure and has a great impact on the mechanical properties of the material. As the average pit depth is an important index to evaluate the degree of pitting corrosion of materials, the study of

A new type of silica-induced “moundless” pitting corrosion in copper observed in Japan

open access: yesHeliyon, 2022
A new type of pitting corrosion in copper, namely “moundless” corrosion, has recently been reported in Japan. This type of pitting corrosion has some unique morphological features that differ from ordinary types of pitting corrosion, such as type I or ...

Study of Corrosion Pit Propagation in Aluminum by Numerical Simulation using the Finite Element Method

open access: yesInternational Journal of Electrochemical Science, 2021
Pitting corrosion is a localized form of corrosion that can restrict the lifetime of a metal. Studying the pitting corrosion is required to predict and prevent the risk of damage of metals susceptible to corrosion.
