Corrosion behavior of magnesium, aluminum and zinc in 0.2 mol dm-3 NH4Cl; 0.1 mol dm-3 NH4Cl with addition of 0.1 mol dm-3 Na-citrate and corrosion behavior of zinc in 0.3 mol dm-3 NH4Cl with addition of 0.8 mol dm-3 Na-citrate and different concentration of ZnCl2 were investigated. Corrosion current densities were determined from the mass lost and from potentiodinamic (1 mV s-1) measurements. It was concluded that magnesium and aluminum are not suitable anodic materials for use in primary electrochemical power sources. On the other hand, it was concluded that zinc could be considered as possible anodic material in both primary and secondary electrochemical power sources.
