The purpose of the work is to study the regularities of the processes of obtaining composites on a copper basis, which is strengthened by dispersed particles and synthesized phases formed during the interaction of the melt with the components of Cu-Fe-C-metal systems, to develop the processes of obtaining composite materials having improved tribotechnical properties. The list of the following tasks was solved for the realization of the purpose and the set goals of this work: - analysis of existing methods of production of alloys on the basis of systems with bundles; - study of the tendency of the Fe-Cu system to stratify under the action of accelerated cooling from the state of a homogeneous liquid solution and doping with other chemical elements; - the features of solid-state equilibrium in the Fe-Cu-C system, in particular, structural and kinetic features in monotectic stratification, and diffusion processes of mass transfer; - the aspects of the influence of alloying elements that are added to the solid and liquid phases on the structural and kinetic regularities of solid-liquid interaction are studied; - morphological peculiarities of formation and crystallization of dispersed phases formed at the interface of solid-liquid interaction are investigated; - solid-liquid interaction of multicomponent melts of real copper alloys in the context of their interaction with industrial iron alloys has been studied; - the established laws have been applied to create the technology of production of new tribotechnical products, which in their value and properties are competitive with the existing modern technological solutions. The proposed new methods of production of tribotechnical products based on the system Fe-Cu-C-x with stratification in the liquid state are based on the revealed patterns of solid-liquid interaction and are alternative to the traditional methods of obtaining LMB by casting, impregnation, surfacing. The advantages of the proposed technological solutions are their cost-effectiveness and ease of implementation. Technological solutions can be extended to manufacture products by contacting functional materials based on iron, magnesium aluminum, etc., to create special purpose composite products.
