Abstract

Current efficiency of the Al-5Zn-0.03In-1Mg-0.05Ti-0.5RE that is solution treated at 510 ℃ and 550 ℃ for 10 hours

respectively

was tested in artificial seawater.And the electrochemical behavior of the alloy in 3% NaCl solution was examined by electrochemical impedance method.It is found that current efficiency and open circuit potential as well as operating potential of the alloy are increased after solution treatment

which accelerates the dissolution.
