Anodizing of magnesium alloy in KOH-Al(OH)3 solutions.

Anodizing of Magnesium Alloy Az31 by Alkaline Solution

-Anodizing of AZ 31 Mg alloy was investigate in 3M KOH solution for 10, 20 and 30min. at constant voltage of 5V. Atomic force microscope (AFM) used to investigate the roughness of anodic film formed on the surface while the scanning electron microscope (SEM) was used to determine the morphology of the anodic film, it was found that the roughness of the anodic film is mainly depend on the anodiz...

Improved Technology for Hard Anodizing Dissolution of Aluminum Alloy Part

This paper deeply analyzes the main factors of the dissolved problems arising in the process of aluminum alloy hard anodizing, combined with the specific problems occurring in production practice, introduces in detail the method and thought to analyze and investigate the causes of dissolving, and puts forward targeted improvement technology. This paper is practically instructive and significant...

Corrosion behaviour of friction stir welded AZ61A magnesium alloy welds immersed in NaCl solutions

The extruded AZ61A magnesium alloy plates of 6 mm thickness were butt welded using friction stir welding (FSW) process. The corrosion behavior of the welds was evaluated by conducting immersion test in NaCl solution at different pH value, immersion time and chloride ion concentrations. An empirical relationship was established incorporating pH value, immersion time and chloride ion concentratio...

Microstructure-sensitive investigation of magnesium alloy fatigue

Kinetics of SIMA AZ80 Magnesium Alloy

Semi-solid feedstock of AZ80 magnesium alloy modified by [trace] rare-earth Y element 10 (0, 0.2, 0.4, 0.8 wt.%) were fabricated by [strain-induced melting activation] (SIMA) in the form of 11 extrusion and partial remelting. The effect of Y addition on the microstructure evolution of [the] 12 extruded and [isothermally heat] treated alloy was observed by [using an] optical microscope (OM), 13 ...
