摘要
研究了在纯镁基底上用激光熔覆的镁铝合金A的显微组织,物相结构及腐蚀行为,表明该合金的组成相为α-Al和β-Mg_2Al_3,在界面上则生成了共晶层;合金内生成了多晶结构;合金的腐蚀速率比纯镁低两个数量级。
Mg-Al alloy A has been obtained by laser cladding on Mg substrate. The alloy isConstituted of α-Al and β-Mg_2Al_3. Eutectic phase was formed in the interface between Cladment andSubstrate, polycrystalline structure was observed, Corrosion rate of alloy a is two order of magnitudelower than that of pure Mg.
