Regularities of Electrochemical Formation and Properties of Oxide Films on Titanium–Iron Alloys

Regularities governing the formation and properties of oxide films on titanium–iron alloys containing 10, 20, 32, 45, 60, or 80 at. % Fe are studied by the voltammetry and chronoamperometry methods coupled with local measurements of activation potentials. Dependences of the oxide film thickness on potential are found. Activation potentials for samples with oxide films formed in air and at 5 V decrease with increasing iron content in alloys.
