Corrosion of Mg Alloys

2022
We review the state of the art of Mg alloy corrosion performance and progress towards a Mg alloy with a corrosion rate much less than the intrinsic Mg corrosion rate of 0.3 mm/y in a concentrated chloride solution, and summarise recent developments in the understanding of Mg corrosion. A critical examination of recent claims of Mg alloys with corrosion

Investigating the Use of Mg-3Pb Alloy for Cathodic Protection of Mg Alloys

ECS Meeting Abstracts, 2023
Magnesium alloys possess many interesting properties, including high strength-to-weight ratios, good castability, and excellent biocompatibility. However, its use has been limited because they are also highly reactive and susceptible to corrosion in aqueous environments.

Anodic oxidation of Mg–Cu and Mg–Zn alloys

Electrochimica Acta, 2004
Metastable, solid–solution Mg-0.8 at.% Cu and Mg-1.4 at.% Zn alloys have been anodized up to 250 V at 10 mA cm−2 in an alkaline phosphate electrolyte at 293 K in order to investigate the enriching of alloying elements beneath the anodic films. Rutherford backscattering spectroscopy (RBS) revealed enrichments to about 4.1×1015 Cu atoms cm−2 and 5.2×1015

Surface Alloying of Mg Alloys After Surface Nanocrystallization

Journal of Nanoscience and Nanotechnology, 2008
Surface nanocrystallization using a surface mechanical attrition treatment effectively activates the surface of magnesium alloys due to the increase in grain boundary diffusion channels. As a result, the temperature of subsequent surface alloying treatment of pure Mg and AZ91 alloy can be reduced from 430 °C to 380 °C.

Grain refinement of Mg-3Y alloy using Mg-10Al2Y master alloy

Journal of Rare Earths, 2021
Abstract The as-extruded Mg-10Al2Y master alloy was chosen as a novel grain refiner for as-cast Mg-3Y alloy. Contrast samples of cast Mg-3Y alloy added with pure Al and Mg-Zr master alloy grain refiners were prepared under the same conditions. In this study, the influence of addition amounts of Al2Y and holding time on grain refinement efficiency as ...

Understanding the Corrosion of Mg and Mg Alloys

2018
This article summarizes current, fundamental knowledge of the corrosion of magnesium, and highlights some latest developments. Mg is a most reactive metal. The high available reaction energy, and because the simultaneous exchange of two electrons is forbidden by quantum mechanics, means that there is a highly reactive intermediate that can chemically ...

Alloying behaviors of AgMg, AuMg and AgAl alloys

Journal of Physics and Chemistry of Solids, 1974
Abstract An expression of the structure-dependent energy of simple metal-noble metal binary alloy is given on the basis of the pseudopotential method. The energy is expressed as a sum of three parts; a band-structure energy, an electrostatic energy and a repulsive overlap energy, each of which is characterized by the usual long-range and short-range ...

Heterogeneous nucleation of Mg–Al alloys

Scripta Materialia, 2006
Grain size is one of the most important microstructural characteristics determining the mechanical properties and therefore the service performance of polycrystalline materials. Heterogeneous nucleation involves the addition or in situ formation of potent nuclei in the system to promote nucleation events, leading to a fine grain structure.
