ANODIC POLARIZATION OF CU-FE-S ALLOYS

The mechanism and principal kinetic features of anodic dissolution of sulfidized copper-iron alloys in sulfide-chloride electrolytes were de termined for different electrolyte temperatures and composition under anodic polarization conditions. The rate of alloy dissolution was foun d to increase with increasing electrolyte temperature and chlorine ion content, but decrease with increasing copper content. The optimum con ditions were found to be: copper content in the anode alloy 35-40%, ch lorine-ion content in the electrolyte 40-60 g/liter.
