Abstract

The results of an experimental study of the influence of nanomodifying additives on the structure and mechanical properties of coatings during laser surfacing of a composite powder with a strengthening phase on porous titanium are presented. Titanium alloy of the Ti–V–Al system with a strengthening phase of titanium carbide was used as a surfacing material, and nano-sized refractory titanium nitride powders were used as a modifying additive. An analysis of the morphological and structural characteristics of a deposited single track was carried out, and the influence of modifying additives on the intensity of dissolution of the strengthening phase and the mechanical characteristics of the deposited layer was established
