ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY OF ANODIC PROCESSES ON IRON GROUP METAL SILICIDES IN SULFURIC ACID
The results of the investigation of the impedance of anodic processes on iron group metal silicides (FeSi, Co2Si, CoSi, CoSi2, NiSi) in sulfuric acid solutions have been summarized and analyzed. The mechanisms and the kinetics of the electrode processes on the silicides depending on the nature of the metal and silicon concentration have been discussed. The influence of pH and de-aeration of the electrolyte on the voltammetric and impedance characteristics of the silicides has been considered.
