Potential Sweep

The anodic behavior of the Sn, the Sn8Hg (γ2) phase and the dental amalgam in a chloride solution has been investigated by means of the linear potential sweep and of the intensiostatic pulse method. The results indicate that anodic current varies with chloride concentration and that dissolution occurs prior to passivation of the electrode. The anodic charge needed for the passivation is smallest for the dental amalgam.

It has been found that the dispersion of phases in copper-nickel sulfide-metal alloys influences their electrochemical properties. X-ray diffraction and optical and electron microscopy have been used to study structural characteristics of the samples prepared by crystallization of sulfide melts at different rates of 10÷103 K/s. High-rate cooling of a converter matte leads to the formation of nonequilibrium sulfide phases and a metallic component dissolved in these phases. The electrochemical oxidation of copper-nickel sulfide alloys has been studied by voltammetry with a linear potential sweep. The data point to a reduction of the limiting oxidation currents of the sulfide alloys prepared by high-rate cooling. The compositions of the intermediate phases and solid products of the electrochemical oxidation, which form the passivating layer, have been determined. The electrolysis of dispersed sulfide alloys allows performing the process at low densities of the current and, thus, the diffusion limitations have been removed.
