各種アルコール溶液中のマグネシウム合金の浸食挙動

抄録

Electrode potential and weight loss of the magnesium alloy (AZ-80A) in alcohols were measured. Continiously measuring the electrode potential against platinum, the magnesium alloy is corroded in methyl, octyl and dodecyl alcohols, 1.2-ethanediol, glycerol and phenol at their boiling points. The alloy is uncorroded in water containing methyl alcohol, but is corroded in another water containing alcohols. The alloy has better corrosion resistance than pure magnesium in alcohols.
