Abstract

The article presents the results of a study of the physical and mechanical characteristics of additive coatings obtained by a combination of methods of electrophysical surfacing and electrospark alloying. The issues of structural transformations during the creation of coatings by the method of additive technologies are considered. It has been established that the chemical composition of the electrodes used has a fundamental influence on the strength and tribotechnical characteristics of the coatings. The formation of both superhard phases in the resulting hybrid coatings and phases with a layered structure characterized by high tribotechnical characteristics is observed. The composition of the coatings, the technological modes of their production have a significant impact on the values of the specific surface energy. When using the proposed technology for obtaining coatings, it is possible to form nanostructures in the matrix of additive coatings. The use of this technological method can significantly improve the physical and mechanical characteristics of superhard coatings.
