This paper studies a new way of cladding particles by preliminary mechanical mixing of particles of a refractory material (TiN) with particles of a binding metal (Ti) followed by forming granules containing 20 mass fractions of initial particles of titanium nitride and their further processing in an argon-helium plasma jet in a controlled atmosphere. As a result of experimental studies, a composition powder consisting of spherical particles sized from 0.1 to 40 μm is obtained. The refractory nanoparticles of titanium nitride in it are evenly distributed over the volume of the binding metal (titanium) and completely plated by it. The surface morphology and the internal structure of the particles are studied, the results of X-ray phase analysis are presented, and a map of element distribution over both the surface and volume of the composition particle is obtained. This method of producing nanomodifying compositions helps to improve homogeneity of the distribution of refractory elements in the melt volume, as well as their wettability, which increases the effectiveness of modifying the material properties.
