Abstract

In this paper, we present results of a comparative study of the efficiency of fiber and particle reinforcement in titanium-matrix composites subjected to high-speed mechanical loading. The structure–phase composition of the synthesized materials has been studied using synchrotron radiation. The results demonstrate that, in the case of laser processing, the degree of dissolution of reinforcing fiber is lower than that of fine powder particles. This leads to a decrease in the volume fraction of the forming secondary phases, such as TiC and Ti5Si3Cx, in the case of SiC fiber, and such as TiB2 and TiB in the case of boron fiber. The use of fiber in producing titanium-matrix composite coatings has been shown to ensure an increase in the impact resistance of the coating material.
