Engineering Physics Annotation << Back Analysis of the Morphology and Functional Properties of Ag–C Composite Coatings Formed by Electrovacuum Deposition on a Copper Substrate Romanov D.A., Vashchuk E.S., Pochetuha V.V. In this work, coatings (C-Ag) were applied to a copper substrate using the method of electric explosion spraying. The studies showed that the obtained coatings, with a thickness of 75 to 200 μm, have a pronounced surface roughness. The graphite in the coating consists of both platelike structures and submicron and nanometer-sized globular particles. Additionally, copper oxide particles were found within the coating. A transition layer of a complex structure with a thickness of 100–150 nm is formed at the interface between the coating and the copper substrate. In this layer, the silver has a lamellar structure, while the copper of the substrate has a sub-grain structure. The hardness and Young's modulus of the "coating (Ag-C)/copper substrate" system increase as they approach the interface between the coating and the substrate. The wear resistance of the coating is 2,3 times higher than that of pure copper. The coefficient of friction between the coating and the substrate is almost identical.
