Electrochemical Resistance Noise during Composite Plating

Abstract

A theoretical and experimental study is presented about the resistance variation caused by spherical particles on the flow of current to disk electrodes embedded in an insulating plane. The calculation of the resistance variation was combined with a trajectory analysis to predict the resistance noise caused by nonconducting particles suspended in the flow of a submerged impinging jet. Experimental resistance noise due to liquid‐containing microcapsules was recorded on electrodes located in the flow of the submerged impinging jet. The resistance‐noise signals were obtained in electrolytes containing either ferri‐ferrocyanide or nickel as electroactive species. From the signals either in ferri‐ferrocyanide solution or during the codeposition of microcapsules with nickel, valuable information on the behavior of particles near electrodes was obtained. The possibilities of this method as an electrochemical sensor for in situ detection of particles and control of the electrodeposition of composite coatings are presented.
