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.

Inhibition of Weld Corrosion in Flowing Brines Containing Carbon Dioxide [PDF]

, 2009
The aim of this research was to study the effectiveness of a typical oilfield corrosion inhibitor, which is considered to be a green inhibitor (non toxic to the environment) in controlling internal corrosion of welded X65 pipeline steel in brines ...

Influence of plasma electrolytic oxidation coating on reducing the corrosion rate of dissimilar FSW joint between AA5052 and AZ31 alloys by minimizing effect of different galvanic couple types

Journal of Materials Research and Technology
This study investigated the different aspects of macro/micro-galvanic corrosion behavior of plasma electrolytic oxidation coating (PEO) applied on a dissimilar joint. In this regard, AA5052 and AZ31 were joined by friction stir welding.

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 ...

Micro-galvanic effects and corrosion inhibition of copper-zinc alloys

, 2014
   Med utvecklingen av och tillgången till lokala analysmetoder som kan ge information med en lateral upplösning på mindre än en mikrometer har det blivit möjligt att analysera lokala korrosionsegenskaper hos industriellt viktiga metalliska material och relatera dessa egenskaper till mikrostrukturen hos samma material.

Effect of iron and manganese on the corrosion resistance of contaminated secondary Al-Si-Mg cast alloys

npj Materials Degradation
It is well established that micro-galvanic corrosion induced by impurity phases during metallurgical processing limits the application of recycled aluminum. This study investigates the corrosion behavior of AlSi7Mg0.3 alloy with two varying Mn/Fe ratios.

Seeking Attention: Economies, Modes, Ecologies

Transactions of the Institute of British Geographers, Volume 51, Issue 4, December 2026.
ABSTRACT Concerns about attention in the current era call for geographic approaches that contend with attention's important place in socio‐spatial life. To this end, this paper first notes that ‘economies’ have emerged as the most prevalent frame for geographic analyses of attention to date but warns that the dominance of such frameworks might close ...
