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

Białobrzeski A., Saja K., Żmudzińska M.

Archives of Foundry Engineering

2011

Vol. 11, iss. 3 spec.

21--24

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.

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

Białobrzeski A., Saja K., Żmudzińska M.

25--28

The article discusses studies and corrosion tests of binary Mg-Li alloys for plastic forming examined in an acid medium (5% HCl solution) for the time of 0-144 hours. In short it can be stated that corrosion of the examined Mg-Li alloys in 5% HCl solution proceeded in a similar mode in all the studied alloys, regardless of the lithium content.

Corrosion behaviour of binary Mg-Li alloys for plastic forming

Białobrzeski A., Saja K., Żmudzińska M.

Archives of Foundry Engineering
