Abstract

Composite materials and coatings that contain titanium diboride in a metal host are widely used with the purpose of fabricating high-strength heat-resistant materials. Due to high hardness as well as heat and corrosion resistance, titanium diboride is a promising compound for use as a wear-resistant component of the composition "metal host-TiB2." The structure and mechanical properties of compositions TiB2-PG-10N-01 and TiB2-PKh20N80, which were obtained by a three-stage method involving the preliminary mechanical treatment of mixtures of elemental powders, the self-propagating high-temperature synthesis (SHS) reaction initiated in the activated mixture, and the subsequent mechanical treatment of the product of the SHS reaction, are investigated. To form the coatings, the method of electron-beam welding is applied.
