Corrosion behaviour of magnesium lithium alloys in NaCl solution

摘要

This work includes the comparison between corrosion resistance of MagLi4, MgLi7.5 and MgLi 15 alloys in sodium chloride (0.15M NaCl) solution at 37℃. Results showed that the corrosion resistance is strongly determined by lithium content in the alloy. The worst corrosion resistance is typical for MgLi7.5 where the dual phase structure is observed. The magnesium -lithium alloys which contain less than 5% of Li and more than 11% (one phase structures) has got better corrosion resistance than dual phase structure magnesium - lithium alloys.
