Influence of Ca on microstructure and corrosion resistance of Mg-14Li alloy
In order to improve the corrosion resistance of magnesium lithium alloy, Mg-14Li alloy with different content of Ca (0, 3, 5, 10wt.%) was prepared with a induction melting furnace. Electrochemical test and corrosion test were carried out in NaCl solution with different Cl- concentrations. The result...
