Studies of corrosion behaviour in alkaline environment of binary Mg-Li alloys for plastic forming

The article discusses studies and corrosion tests of binary Mg-Li alloys for plastic forming examined in an alkaline medium (5% NaCl solution) for the time of 0-144 hours. In short it can be stated that the increase of Li content in magnesium alloys from 3% to 9% increases the corrosion resistance of alloy (the lowest susceptibility to corrosion in NaCl solution showed Mg- Li9 alloy). Increasing the content of Li in alloy to over 9% resulted in a significant increase of the susceptibility to corrosion.
