Oxidation of magnesium alloys at elevated

2016-11-1  High temperature oxidation of a Mg alloy in air is typically associated with a change of the microstructure and melting of second phases. The eutectic temperature of the Mg-Al system is 437 °C. Above this temperature in Al-rich Mg alloys,

Microarc oxidation of magnesium alloys: A review

This review summarizes the experience of using plasma electrolyte methods to improve the properties of magnesium alloys intended for designing components of various devices, medical equipment, etc. The emphasis is placed on the formation of coatings by both the “standard” microarc oxidation (MAO) method and its version using electrolytes containing suspended

Introduction to Magnesium Alloys ASM International

2017-12-14  works, consider magnesium alloy AZ91E-T6. The first part of the designation, AZ, signifies that aluminum and zinc are the two principal al-loying elements. The second part, 91, gives the 0.001 wt%) to decrease surface oxidation when melting, casting, and welding alloys. It is suc-cessfully used in die-cast and wrought products

Plasma Electrolytic Oxidation of Magnesium Alloy

Plasma electrolytic oxidation (PEO) coatings were produced on AZ31B magnesium alloys in alkaline electrolytes with the addition of various concentrations of Al2O3 sols. Effects of Al2O3 sol concentrations on the microstructure, phase

The high-temperature oxidation resistance properties

A stable oxide film was formed on the alloy surface and limited further oxidation. The oxide film was composed of Gd2O3, MgO and MgCO3 for Mg-3.5Gd and was mainly CaO and CaCO3 with increasing Ca

Corrosion Resistance of Micro-Arc Oxidation/Graphene

2020-8-6  corrosion resistance of magnesium alloys.6,7 Micro-arc oxidation (MAO) technology is a promising surface treatment conducive to the corrosion protection of the magnesium alloy substrate.14,15 In order to improve the corrosion GO is usually used in the experiment because it is easy to chemically attach graphene sheets onto a bulk substrate

Micro-arc oxidation behavior of fly ash cenospheres

2020-6-15  In order to reduce the degradation rate of fly ash cenospheres (FACs)/magnesium alloy (MA) degradable composite, the protective micro-arc oxidation (MAO) coatings were prepared on the composite. The corrosion resistance of the coatings was evaluated by immersion tests and potentiodynamic polarization tests in 3 wt% KCl solution.
