Description
純粋マグネシウム(99.5%Mg)を低炭素鋼ルツボに装入し、保護ガス雰囲気下で720℃に昇温して前記純粋マグネシウムを溶解した。その後、前記純粋マグネシウムが完全溶解された時、融点が高い母合金から前記純粋マグネシウムに添加した。この時、合金元素が十分に混合されるように前記合金溶湯を10分程度攪拌した。その後、前記合金溶湯内介在物を沈降させるために10分程度維持して合金溶湯を準備した。
比較例1は常用のAZ31系マグネシウム合金を準備した。
(腐食速度の評価方法)
前記実施例と比較例の腐食速度を測定して耐食性を評価した。
機械的物性は、ASTM E8規格によりGage length 25mm板状試片を利用して10-3/sの変形率速度条件で常温引張試験を実施して降伏強度、引張強度および延伸率を測定した。
