Results are provided for a study of the anodic behavior of aluminum alloy AK7 and composite material of the Al–Al2O3 (Oxidal) system in an electrolyte medium of 0.03, 0.3, and 3.0% NaCl. Corrosion-electrochemical study of alloys shows that with an increase in chloride ion concentration within electrolyte alloy corrosion rate increases by a factor of 1.3–1.7. It is shown that composite material of the Al–Al2O3 system has better corrosion resistance than the original AK7 alloy. At the same time, alloy pitting resistance also increases, as shown by the shift in pitting and corrosion potentials into a positive range of values.
