Kulynych V. Ensuring wear resistance of a stamp tool using self-propagating high-temperature synthesis processes

The article considers the current issues of implementing innovative technologies for applying protective and strengthening coatings on the surface of a stamping tool using the method of self-propagating high-temperature synthesis (SHS). The authors analyze the problems of resource conservation in industry associated with the use of expensive alloyed alloys and propose an alternative approach - the formation of coatings with specified properties, which allows reducing the cost of production without losing operational characteristics. The study separately considers the influence of such parameters as porosity, dispersion of components, concentration of alloying additives, burning rate, as well as the influence of external factors (temperature, electric and magnetic fields, pulsed currents) on the quality and structure of coatings. Considerable attention is paid to rapid crystallization methods, which allow obtaining metastable and amorphous materials with unique properties, in particular increased corrosion resistance and specific strength. The role of shock wave loading as a method of creating a defective substrate structure that stimulates diffusion processes and enhances adhesion between the base material and the coating is analyzed. The main goal of the work is to develop and justify the technological parameters of the SHS process to obtain protective coatings with specified physical and mechanical properties while minimizing the use of expensive components. The results obtained may be useful for the implementation of effective resource-saving technologies in the manufacture of stamping tools, as well as for further research in the field of materials science.
