Atmospheric Corrosion Protection of LPBF Manufactured AlSi10Mg by Combining SiOx‐CVD and PDMS Grafting

open access: yesMaterials and Corrosion, EarlyView.
Hybrid SiOₓ‐CVD/PDMS ultrathin films mitigate atmospheric corrosion of additively manufactured AlSi10Mg. Electrochemical analyses show reduced corrosion currents, increased charge‐transfer resistance, and suppressed pitting due to diminished cathodic activity and limited oxygen and ion transport under NaCl exposure.

Visualizing Metal Nanoparticle Electrochemical Dissolution Atom by Atom

open access: yesSmall, EarlyView.
The early stages of the electrochemical dissolution of gold nanoparticles (NPs) on electron beam transparent carbon‐based supports are investigated using identical location scanning transmission electron microscopy at atom resolution. Numbers of atoms lost (and gained), along with morphology changes are tracked for the same NP within an ensemble, over ...

Influence of Heat Treatment Temperature on Crevice and Pitting Corrosion of UNS S32205 Duplex Stainless Steel

open access: yessteel research international, EarlyView.
Heat treatments that alter the proportions of austenite and ferrite phases or induce the precipitation of phases such as sigma in duplex stainless steel UNS S32205 make it more susceptible to pitting and crevice corrosion. However, the effects of these treatments are not always evident when analyzed using the cyclic polarization technique.

Mechanical, rheological, and durability performances of GGBS‐based concrete for potential application to prestressed structures

open access: yesStructural Concrete, EarlyView.
Abstract Ground granulated blast‐furnace slag (GGBS) is a widely used clinker substitute in concrete, recognized for its potential to significantly reduce environmental impacts. However, its application in prestressed concrete remains limited in several countries, mainly due to concerns regarding early‐age mechanical performance and long‐term ...
