摘要: A magnesium alloy structural member having excellent corrosion resistance is provided. The includes a substrate that contains more than 7.5% by mass ofAl and an anticorrosive layer formed on surface of the chemical conversion treatment. precipitate, typically, particles dispersed therein. are made intermetallic compound containing at least one Al Mg have average particle size 0.05 µm or 1 less. total area accounts for 1% 20% lower sublayer in this order. denser sublayer. has high because content. dense front side layer, which prevents corrosive liquid from reaching substrate. porous can reduce tendency to detach substrate, example, upon impact allows retain resistance.
