Abstract: The influence of substrate preheating on the structure of a cermet-coating obtained by direct metal deposition from Ti64 alloy reinforced with B$_4$C particles. Coatings containing 15%. B$_4$C were obtained for the first time. It has been shown that the use of substrate preheating makes it possible to produce cermet coatings without cracks. It has been found that in tribological tests, that the scratch volume of the cermet coating decreases by a factor of eight compared to the coating with the content of B$_4$C 10%.

Keywords: Ti–6Al–4V alloy, substrate preheating, boron carbide, hardness, wear resistance, microstructure.
