Magnesium Mg alloys in ethylene glycol solution

Magnesium alloys should have a similar corrosion behaviour to that of pure magnesium in an ethylene glycol solution. This has been eonfirmed by Fekry and Fatayerji s systematic study [30], which is briefly deseribed as follows. 

Secondly, chlorides in the ethylene glycol solution have a detrimental effect on the corrosion of AZ91D. When the concentration of chlorides is over 0.05 M, an evident corrosion acceleration effect is measured (see Fig. 11.7). The anodic polarization current density increases dramatically with increasing chloride concentration in the solution.
