摘要
采用M351测量系统测试了8090铝锂合金在3.5％NaCl溶液中的腐蚀行为，并用SSRT测试技术研究了阴极极化下合金的氢脆敏感性，结果表明：充氮介质和时效制度对合金的氢脆敏感性影响较大，强烈渗氢条件下，氢可能成为腐蚀断裂的主要因素．
The poldrization curve of Al-Li alloy 8090 was measured by electrochemical measuring device M351, and the hydrogen embrittlement susceptibility of Al-Li alloy was evaluated with slow strain rate technique. The experimental results showed that the aging conditions and the penetrating medium had profound effects on the HES of Al-Li alloy. Hydrogen embrittlement could play a dominant role in corrosion cracking as the hydrogen heavily permeated into the materials.
