ELECTROCHEMICAL METHOD FOR CONTROL OF DIELECTRIC QUALITIES OF ALUMINUM OXIDE FILMS

摘要

An electrochemical method for control of oxide films dielectric qualities, which are formed from aluminum. Anode polarization is fulfilled when cyclogram readmission to potentials more positive than potential of previous cycle finishing for a magnitude allowing fulfillment of estimation of dielectric characterization according to limiting current, changing of its magnitude from cycle to cycle and difference between potentials of finishing previous cycle and beginning the next cycle.
