Mechanism of Corrosion Protection of Anodized Magnesium Alloys

A 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...

Corrosion Protection of Magnesium Alloys in Industrial Solutions

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...

Corrosion and Protection of Magnesium Alloys - A Review of the Patent Literature

Magnesium (Mg) and its alloys posses low density, high specific stiffness and electromagnetic shielding property, which are attractive to the automobile industry, 3C (computer, communication, consumer electronics), military and aerospace industry. Mg alloys have relatively low open circuit potential and thus highly susceptible to galvanic corrosion when they are in touch with other metal materi...

Bio-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...
