The current efficiency during the cathodic period of reversing current in copper powder deposition and the overall current efficiency

Abstract

The current efficiency during the cathodic period of reversing current in copper powder deposition was determined by measuring the quantity of hydrogen evolved. The diagrams from which the instantaneous and average current efficiencies for copper deposition can be extracted for any deposition time up to 30 min are given. A procedure for the calculation of the overall current efficiency is proposed.

Određivano je iskorišćenje struje za vreme katodnog perioda reversne struje pri taloženju bakarnog praha, merenjem količine izdvojenog vodonika. Dati su dijagrami iz kojih mogu biti izračunata trenutna i srednja iskorišćenja struje za taloženje bakarnog praha, za bilo koje vreme taloženja do 30 minuta. Predložen je postupak proračuna ukupnog iskorišćenja struje.
