СИНТЕЗ МНОГОКОМПОНЕНТНЫХ И МНОГОФУНКЦИОНАЛЬНЫХ ПОКРЫТИЙ В ПЛАЗМЕ НИЗКОВОЛЬТНОГО ИМПУЛЬСНОГО РАЗРЯДА

Abstract

The synthesis of multicomponent and multifunctional coatings in low-voltage discharge plasma using compact electrodes made of graphite, refractory metals such as titanium, tantalum and tungsten, as well as their powders has been studied. Optimised energy regimes (energy value of electric discharges) have been identified at which the most qualitative coatings (uniform and continuous) with the highest content of carbide phases were obtained, which provide high hardness and service life under wear conditions. The utilisation of powders as alloying materials in lieu of compact electrodes has enabled the attainment of significantly thicker coatings and an enhancement in the process's productivity. This will facilitate the expansion of the technology's potential applications.
