We investigated plating of chromium at direct (0,1-1 A/cm2) and pulse (0,1-0,4 A/cm2) current from standard chromic electrolyte. The pulse plating was carried out at a duty cycle ~ 0,3. Duration of a pulse varied in range 200 s – 200 s. We demonstrate that at temperature of chromium plating 50C pulse plating allows to increase a current efficiency up to ~ 40%. We determined conditions of pulse plating, at which current efficiency falls with increasing current density. In this case better throwing and covering power of electrolyte is observed. |
