Corrosion behaviours of Ti6Al4V-Mg/Mg-Alloy composites

Corrosion Science, 2020
Abstract The effect of coupling of unalloyed Mg and Mg-alloys (AZ91 and WE43) with Ti6Al4V alloy on corrosion and degradation behaviours of produced composites has been investigated in simulated body fluid (SBF) by hydrogen evolution, and surface and electrochemical characterization techniques.

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.

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 ...

Superhydrophobic ZIF-8 based dual-layer coating for enhanced corrosion protection of Mg alloy.

ACS Applied Materials and Interfaces, 2020
Magnesium (Mg) and its alloys are regarded as the most promising engineering materials due to their unique property. However, the Mg alloys were easily corroded in humid environments, which restricted their wider application. Herein, the superhydrophobic

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 ...

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.

Metallography of Mg Alloys

2019
Processing and composition determine microstructural properties. To reveal the microstructure, the metallographic investigation is a commonly used method, and therefore, it is a crucial part in the characterization of metals and alloys. Choosing incorrect preparation steps will lead to artefacts and misleading conclusions due to the compositional ...

High Energy Micro-Arc Alloying of Mg-RE on AZ31 Mg Alloy

Advanced Materials Research, 2011
Mg-RE electrode was used for deposition of micro-arc coatings on AZ31 magnesium alloy upon variation in there different processing parameters(high, low and middle pulsed discharges). Mass transfer trends from electrode to substrate and microstructure of Mg-RE coating on AZ31 substrate were observed. Characterization has been performed by using scanning
