文摘
- •
The oxidation resistance of Mg–2.5Y, Mg–2.5Y–2.5Al and Mg–2.5Y–4.2Al was compared.
- •
Solid-solute Y element can benefit to improve the oxidation resistance of Mg.
- •
Stable existing Al2Y compound will deteriorate the oxidation resistance of magnesium alloys.
- •
Oxide films were characterized by SEM, XRD and XPS techniques.
- •
Y2O3 and Al2O3 are formed prior than MgO during oxidation process.
