Abstract

Formulation of the problem. Study of the effect of the electrodeposition regime, geometry and size of graphite particles used as a filler in cobalt deposits on surface morphology of a composite 3…15 μm thick cobalt − graphite electrolytic coating. The surface morphology of a composite 3…15 μm thick cobalt − graphite electrolytic coating was studied. Findings. The influence of the deposition regime, geometry and particle size of graphite on surface morphology of a composite 3…15 μm thick cobalt − graphite electrolytic coating is revealed. It is established that to obtain cobalt − graphite composite electrolytic coatings with a continuous layer of cobalt deposits, it is necessary to use graphite, which is pre-applied by an electrocontact method on the substrate before electrodeposition and also particles being formed as a result of destruction of the graphite anode during electrolysis. Originality. The effect of the deposition regime, geometry and size of graphite particles on surface morphology of composite cobalt − graphite electrolytic coatings is discussed. Practical value. The results of the investigations make it possible to obtain a composite 3…15 μm thick cobalt − graphite electrolytic coating with a continuous layer of cobalt deposits.
