| Popis: | Electrochemical and electrophysical properties of surface layers formed on VT1–0 titanium in phosphate electrolyte with the current in zones of oxide-layer breakdown limited due to the use of a phenomenon of electromagnetic induction, that allows one to control the energy supply to breakdown channels, are considered. It is shown that coatings synthesized with external regulation of reactive resistance differ from those formed without limiting the energy by taking smaller concentrations of charge carriers and a higher electric resistance. The galvanic couples that involve samples with films formed this way demonstrate the lower contact corrosion current as compared with samples treated without limitations for energy in the breakdown zones. |
