Anodic Processing of Non-Ferrous and Precious Metal Alloys in The Chloride Solution

Abstract

The rate of anodic dissolution and dependence of current of partial components of the current density Dа for alloys with different Au, Аg and Cu contents have been studied. At high Dа both components of alloy etched with equal rate, whereas at low Dа region of selective dissolution of electronegative components (Аg, Cu) has been observed, a top boundary of which rises with the increasing of Cu contents in the alloy
