The paper presents the results of investigations of the structure and phase composition of titanium boride coatings deposited by magnetron sputtering from a target of a complex composition onto a steel substrate. The target for magnetron sputtering was obtained by sintering boron carbide and titanium powders. The structure and elemental composition of the coating were studied using X-ray diffractometry (XRD), scanning electron microscopy (SEM) and the energy-dispersive spectral (EDS). It was established that the coating structure is a mixture of Ti 2 B 5 and TiB 12 phases with the total boron content of ≈ 80 at %, which is 4 times higher than the boron concentration in the coatings obtained by plasma spraying of the B 4 C powder. The use of magnetron sputtered coatings of titanium boride coatings as neutron-absorbing materials will allow to reduce the coating thickness in comparison with the coatings from boron carbide synthesized by plasma spraying methods.
