Electrochemical composite coatings allow successfully solving many practical problems of surface-hardening of structural parts and their tooling components, as well as renewing their fast-wearing components. Electrochemical chromium-matrix composite coatings are used to enhance the thermal and wear resistance of steel articles and parts operating in friction conditions and under increased temperatures, but under low shock loads.
This paper presents the results obtained from studying how fine black carbon particles affect the properties of composite coatings. Optimal conditions are found for producing high-quality coatings, such as the suspended electrolyte mixing rate and graphite concentration in electrolyte. We have also studied how heat treatment affects the microhardness and surface morphology of coatings. High-dispersed black graphite can be used to produce chromium-matrix composite coatings having increased microhardness and wear resistance.
