The work presents the results of the study of the anodic behavior of aluminum alloy E-AlMgSi (aldrey) with gallium, in the medium of 0.03; 0.3 и 3.0% NaCl electrolyte. The corrosion-electrochemical study of alloys was carried out using the potentiostatic method. It was shown that doping E-AlMgSi (aldrey) with gallium increased its corrosion resistance by 20%. The main electrochemical potentials of the alloys when doping with gallium are shifted to the positive range of values, and at the concentration of sodium chloride to the negative values of the ordinate axis.

The solid lithium electrolytes in the system Li4-3xGaxGeO4 were synthesized and studied. The introduction of Ga3+ ions into lithium orthogermanate leads to the formation of γ-Li3PO4 type structure and sharp increasing of conductivity which have the maximum at x = 0.10÷0.15 and reach ~ 10-1 S·cm-1 at 300°C, > 1 S·cm-1 at 600°C. The main current carriers are interstitial lithium cations which have the weak connection with rigid skeleton of structure. Results are compared with the earlier obtained date on the similar aluminum containing system.
