TiB / 30 wt.% Ti layered composite material obtained by free SHS compression on a Ti6Al4V titanium alloy

Abstract

In this work, a layered composite material based on TiB/30 wt.% Ti on a Ti6Al4V titanium alloy was obtained by free SHS compression. Powders of titanium and amorphous black boron were used as initial components. The structural features, phase composition, porosity and distribution of microhardness along the height of the layered material were studied. It was shown that, as a result of synthesis and subsequent high-temperature deformation, the following phases were formed in the layered composite material: TiB, TiB2, Ti0, 76N. It was found that at a compression pressure of 50 MPa a layered composite material with a porosity of up to 1-2% is formed. It was found that the delay time before applying pressure affects the size of the diffusion zone in the range of 10-50 microns. Due to the formation of hardening phases in the composite material on Ti6Al4V, the microhardness of its surface increased from 2.4 to 11 GPa.
