研究了Mg-12Li-3Al合金在3.5%NaCl溶液中的腐蚀行为。结果表明,Mg-12Li-3Al合金的腐蚀产物为Mg(OH)2、β-Li和Al(OH)3。随着腐蚀时间的增加,合金的腐蚀从化合物聚集的晶界逐渐扩展到整个晶粒内部。
The corrosion behavior of Mg-12Li-3Al alloy in 3.5% NaCl solution was studied. The results show that the corrosion products of Mg-12Li-3Al alloy are Mg (OH) 2, β-Li and Al (OH) 3. With the increase of corrosion time, the corrosion of the alloy gradually spreads from the grain boundaries where the compounds are aggregated to the entire grain interior.
