-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...

The use of bioabsorbable metals as temporary medical implants has attracted considerable research interest they do not require a second surgical operation for removal after the healing process is completed. However, magnesium (Mg) and its alloys have degradation rate that too high in biological environments. Therefore, it must be controlled using various strategies. In this study, an AZ31-Mg-ba...

Magnesium is an abundant material with high specific strength, and its use as a structural metal increasing. However, properties cause difficulty in formation at room temperature. Therefore, the objective of this study was to form magnesium alloy temperature using underwater shock wave generated by discharge aluminum wire. Forming conducted auxiliary plate composed instead alone. In addition, h...

Magnesium alloys have found widespread applications in diverse fields such as aerospace, automotive, bio-medical and electronics industries due to its relatively high strength-to-weight ratio. However, stress corrosion cracking of these alloys severely restricts their applications in several novel technologies. Hence, it will be useful to identify the corrosion mechanics of magnesium alloys und...

Abstract This study aims to analyze the influence of process parameters used for hydrothermal synthesis CaP coatings on their properties and improve corrosion resistance biocompatibility compared substrat AZ31. The monitored were deposition time, pH reaction mixture, concentration precursors in mixture. For deposited AZ31 magnesium alloy, surface morphology number structural defects evaluated u...

Magnesium alloys are receiving increasing attention as a structural material in vehicles to reduce weight and increase fuel economy. Understanding the formability of lightweight alloys is one key to their successful introduction in vehicles. We present results of X-Ray diffraction and electron back-scatter diffraction texture measurements in as-cast and uniaxially compressed AZ31 for a variety ...

Abstract Magnesium and its alloys are excellent implant material candidates with their biodegradable structure mechanical properties close to human bone. In order provide the desired strength in applications, corrosion resistance of materials is expected be high. this study, improve AZ31 AZ91 magnesium alloys, an electrostatic hydroxyapatite coating process was applied, optimum conditions were ...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...
