This paper aims to review the studies of electrochemical properties of Me – Si binary systems for scandium, titanium, molybdenum, manganese, iron, cobalt, nickel, copper and zinc from the point of view of chemical thermodynamics.  The phase diagrams of Me – Si and Me – O systems were considered and thermodynamic properties of metals silicides and oxides at standard conditions were collected. The potential – pH diagrams of Me – Si – H₂O systems at 25ºC, air pressure of 1 bar and activities of ions in solution equal to 1 mol l^–1 were plotted. The corrosion-electrochemical behaviour of studying systems was discussed.
