FIELD: producing oxide layer on anodes of oxide-semiconductor and electrolytic capacitors. ^ SUBSTANCE: proposed method depending on electrochemical treatment of anodes disposed in electrolyte filled bath includes molding of anodes under electrostatic condition, evaluation of electrolyte resistance at beginning of electrostatic condition continued until voltage across bath rises by voltage drop across electrolyte resistance, this being followed by transfer to voltage regulation in electrolyte filled bath while maintaining anode voltage at value equal to oxidation voltage; in the process electrolyte resistance in Ohm is found from formula Re = U0/Id, where U0 is voltage across electrolyte filled bath at beginning of electrostatic condition, V; Id is process-desired current, A; voltage across electrolyte filled bath is regulated using formula Ub = Uox + Ia x Re, where Ub is voltage across electrolyte filled bath, V; Uox is oxidation voltage, V; Ia is actual value of anode current, A; Re is electrolyte resistance, Ohm. ^ EFFECT: reduced time taken to produce oxide layer on anodes of oxide-semiconductor and electrolytic capacitors. ^ 3 cl, 3 dwg |
