PROCESS OF PULSE ELECTROCHEMICAL GLAZING OF GOLD AND ITS ALLOYS

摘要

electrochemical finishing treatment of surfaces. SUBSTANCE: process refers to electrochemical glazing of complex-profile surfaces. Treatment is carried out by pulse unipolar current of rectangular form in the course of 5-20 s in electrolyte containing: tiocarbamide 90.0 g/l; concentrated sulfuric acid 70.0 g/l with following parameters of technological current: duration (0,5-2).10-3 s, relative pulse duration 1.25-5.0; amplitude density of current (5.0-10.0) A/sq.cm and electrolyte temperature 18-22 C. EFFECT: raised productivity and improved quality of surface glazing.
