Corrosion and Surface Treatment of Magnesium Alloys
The need for fuel efficiency and increased performance in transportation systems continually places new demands on the materials used. The design criteria which automobile and aerospace industries are primarily concerned with are density, strength, stiffness, and corrosion resistance. Low-density materials may reduce fuel costs, increase range, and allow larger payloads. High strength and stiff...
متن کاملMitigation of Corrosion on Magnesium Alloy by Predesigned Surface Corrosion
Rapid corrosion of magnesium alloys is undesirable in structural and biomedical applications and a general way to control corrosion is to form a surface barrier layer isolating the bulk materials from the external environment. Herein, based on the insights gained from the anticorrosion behavior of corrosion products, a special way to mitigate aqueous corrosion is described. The concept is based...
متن کاملA Review of Magnesium/Magnesium Alloys Corrosion and its Protection
A review is provided about the current research on magnesium/magnesium alloys corrosion in the industry. Except for reviewing the kinds of corrosion on galvanic corrosion, stress corrosion, and corrosion fatigue, its corresponding mechanisms are also explained, such as the influence of metallurgical factors, and environmental factors. Furthermore, the protection of magnesium/magnesium alloys co...
متن کاملCorrelation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys
* Corresponding author. Tel: 34 1 3944348; Fax: 34 1 3944357 E-mail: [email protected] ABSTRACT X-ray photoelectron spectroscopy (XPS) was used in order to investigate the correlation between the surface chemistry and the atmospheric corrosion of AZ31, AZ80 and AZ91D magnesium alloys exposed to 98% relative humidity at 50oC. Commercially pure magnesium, used as the reference material, reveale...
متن کاملBio-Corrosion of Magnesium Alloys for Orthopaedic Applications
Three Mg alloys, Mg-1.34% Ca-3% Zn (MCZ), Mg-1.34% Ca-3% Zn-0.2% Sr (MCZS), and Mg-2% Sr (MS), were examined to understand their bio-corrosion behavior. Electrochemical impedance spectroscopy and polarization scans were performed after 6 days of immersion in cell culture medium, and ion release and changes in media pH were tracked over a 28 day time period. Scanning electron microscopy (SEM) of...
