A Review of Magnesium/Magnesium Alloys Corrosion and its Protection
نویسنده
چکیده
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 corrosion is presented, for instance, surface treatment/modification, coating and so on. Also, because the continuing challenges associated with the use of magnesium alloys, more considerations about future applications and research directions are given according to the properties improvement of magnesium alloys for the eco-friendly requirements.

The Effect of Environmental Parameters on the Corrosion Behavior of Simple Shear Extruded AZ91 Magnesium Alloys
In this study, the effects of forming method (extrusion) and environmental factors (solution pH and temperature) on the corrosion performance of AZ91 magnesium alloys were investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and salt spray techniques. The polarization test results of the specimens showed that simple sh...
متن کاملCorrosion 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...

Polymeric film coatings were applied by dip coating on two magnesium alloy systems, AZ31 and Mg4Y, in an attempt to slow the degradation of these alloys under in vitro conditions. Poly(lactic-co-glycolic acid) polymer in solution was explored at various concentrations, yielding coatings of varying thicknesses on the alloy substrates. Electrochemical corrosion studies indicate that the coatings ...
