Abstract
An alloy member includes a base material having magnesium as a main component and containing lithium, and an anti-corrosion film that is provided on the base material and contains magnesium, phosphorus, and fluorine. An average film thickness T of the anti-corrosion film is 20 μm or more, and a difference between a maximum value and a minimum value of a film thickness of the anti-corrosion film is less than 20 μm.
Claims19
An alloy member, comprising:
- a base material having magnesium as a main component and containing lithium;
- and
- an anti-corrosion film provided on the base material and containing magnesium, phosphorus, and fluorine,
