In the production of reinforcing ropes, the patenting of wire rods is carried out under the technical production regulations. Patenting is a consequence of isothermal treatment, in which the decomposition of supercooled austenite is carried out in the lower part of the temperature range of diffusion transformation. In the microstructure of patented steel, there should be no structures of prostate, bainite, and martensite. Such a structure has a combination of ductility as well as good deformability with high reduction ratios. In the production of ropes, failure to comply with these technical requirements can lead to serious consequences. The article examines the defects that have arisen in the production of reinforcing ropes. In the course of the study, on the surface where the wires broke, uneven colors, scratches, and small flaws were revealed. For microstructural analysis of the metal was used Microscope Altami MET 1C. As a result of the microstructural study of steel, areas with large-lamellar perlite were identified, which led to a wire break.

This article deals with studying the technology of electric arc spraying of the eccentric body by selection of the copper-steel pseudo-alloy for spraying a covering. The part durability with the placed covering depends on the technology of spraying and the properties of the sprayed material. By increasing the strength of adhesion of the covering to the base it is possible to establish the optimal indicators of the coating mode. It became the main criterion of studying the arc spraying technology from the mathematical point of view.
