Abstract
This article presents the results of a study on the influence of mechanical activation parameters on the morphological, thermal, and phase characteristics of multicomponent Ti+SiC and TiCN+Si powders intended for the formation of functional coatings via reactive plasma spraying (RPS). A comprehensive analysis of the structural and property changes of the powders depending on activation time was carried out using scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and X-ray diffraction (XRD). It was established that the optimal activation time is 60 minutes, at which the best combination of characteristics is achieved: reduction in particle size, decreased agglomeration, enhanced thermal stability, and formation of highly crystalline phases. These activation conditions were found to promote the synthesis of new functional phases, increasing the reactivity and homogeneity of the composite. The obtained results have practical significance for the development of nanostructured wear- and heat-resistant coatings for components operating under high temperatures and mechanical loads, particularly in industries such as mechanical engineering, energy, and aerospace.
