Corrosion Analysis of Rapidly Solidified and Subsequently Aged Al‐Ni and Al‐Fe‐Ni Alloys

Materials and Corrosion, EarlyView.
Fe addition modifies intermetallic phase chemistry and microgalvanic interactions in Al‐Ni alloys, shifting corrosion from generalized dissolution to localized attack. ABSTRACT This study investigates the influence of Fe addition and heat treatment on the corrosion behavior of Al–5 wt.%Ni and Al–2 wt.%Fe–1.5 wt.%Ni alloys, with particular emphasis on ...

Effect of temperature on galvanic corrosion of B30 copper alloy/TA1 titanium alloy galvanic couple in 3.5 wt% NaCl solution

Journal of Materials Research and Technology
The galvanic corrosion behavior of B30/TA1 galvanic couple in 3.5 % NaCl solution was examined using electrochemical noise (EN) analysis, scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), and X-ray photoelectron ...

Role of Si Alloying in the Microstructure Evolution and Corrosion Performance of ZnAlMg Coatings

Materials and Corrosion, EarlyView.
Si alloying refines the coating microstructure and enables formation of Mg2Si. When present at the surface, this phase is the strongest early source of Mg2+, providing short‐term protection, followed by dissolution of MgZn2 and Zn and formation of more stable corrosion products.

Investigation of the Effects of Surface and Heat Treatment on the Corrosion Behavior of Additively Manufactured AlSi10Mg

Materials and Corrosion, EarlyView.
Surface finish and heat treatment strongly affect the corrosion behavior of AM AlSi10Mg. Polished samples show the highest corrosion resistance, while as‐built ones suffer from surface roughness and weak oxide layers. Stress relief (SR300) improves the corrosion potential but lowers pitting resistance due to Si network dissolution.

The Initiation, Progression, and Stifling of Micro‐Galvanic Corrosion on Cu in Anoxic Aqueous Sulfide Solutions

Materials and Corrosion, EarlyView.
In intermediate and high [SH−] solutions, micro‐galvanic corrosion was initiated due to the non‐uniform growth of the Cu2S film. As the film thickened over time, the resistance to Cu transport through the film increased, eventually suppressing micro‐galvanic corrosion and leading to a transition to general corrosion.

Numerical modeling of galvanic corrosion

, 2008
Numerical modeling has become a trend in galvanic corrosion research. We summarize the forms of corrosion and focus on the galvanic corrosion, especially about the corrosion of magnesium and its alloys. We discuss the governing equations and the boundary

Interpretation of galvanic series when teaching metal corrosion

Chemistry Teacher International
The article discusses the knowledge of students in metal corrosion. Usually, resistance of metals against corrosion is determined by the values of the standard electromotive force (EMF) of the metals determined versus the standard hydrogen electrode (SHE)

The Effect of Heat Treatment on the Localized Corrosion Susceptibility of Extruded AA6063 Alloys With High Amount of Tramp Elements

Materials and Corrosion, EarlyView.
In AA6063 variants with increased Cu and Zn contents, T6 heat treatment increased local electrochemical contrast, promoting earlier trenching and more frequent intergranular corrosion initiation. Non‐heat‐treated variants developed fewer but larger intergranularly corroded regions, showing that T6 shifts localized corrosion from propagation toward ...

Rational Design Strategies Toward Efficient and Stable Electrocatalysts for Hydrogen Production via Water Electrolysis: A Comprehensive Review

Small, EarlyView.
ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...
