Abstract
There is provided a magnesium alloy member that includes an aluminum-containing magnesium alloy material. The magnesium alloy material has a modified layer formed at a surface thereof in such a manner that at least a surface of the modified layer has a higher aluminum content than that of any unmodified base portion of the magnesium alloy material.
Claims7
A method of producing a magnesium alloy member, comprising:
- preparing an aqueous lubricant containing an inorganic chloride and at least one selected from the group consisting of monohydric, dihydric, and trihydric alcohols each having a carbon number of 1 to 10 as a surfactant;
- surface treating an aluminum-containing magnesium alloy material with the aqueous lubricant, thereby forming a modified layer at a surface of the magnesium alloy material in such a manner that at least a surface of the modified layer has a higher aluminum content than that of any unmodified base portion of the magnesium alloy material;
- applying an adhesive resin material to at least part of the surface of the modified layer;
- and
- bonding a counterpart material via the adhesive resin material to the surface of the modified layer.
