The corrosion fatigue behavior of magnesium alloy influenced by corrosion inhibitors with the differentiated inhibition mechanisms

open access: yesJournal of Magnesium and Alloys
The effects of three corrosion inhibitors on Mg-Zn-Y-Nd alloy corrosion fatigue were investigated. Salicylic acid (SA) induces uniform but rapid corrosion, limiting fatigue life improvement.

Microstructure Refinement on Crevice Corrosion of High-Speed Rail Steel U75V Visualized by an In Situ Monitoring System

open access: yesFrontiers in Materials, 2022
Rail foot covered by a fastener will suffer from crevice corrosion, leading to thinning and localized attack of crevice interior posing a risk of failure. This work investigated crevice corrosion behavior of a typical pearlitic high-speed rail steel U75V,

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

open access: yesAdvanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

A review of recent developments on the localized corrosion of mild steel used in the oil and gas industry

open access: yesDiscover Materials
Localized corrosion in oil and gas facilities has been a significant challenge due to its catastrophic consequences on pipelines and installations. This is affected mainly by the heterogeneous nature of the environment in which the pipeline and other oil

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Understanding localized corrosion

open access: yesMaterials Today, 2008
The breakdown of a protective passive film leading to accelerated dissolution at localized sites is an important practical issue and a vexing scientific problem. The small dimensions, short timescale, and dynamic interplay between a heterogeneous surface and changing potential and solution concentration gradients complicate the development of a ...
