Abstract: | Coatings on titanium targets are obtained under conditions of a shaped-charge explosion; the maximum microhardness of the
coatings at certain segments of the target can reach 4000 kg/mm2. A conical liner with a cone angle of 20° prepared from a mixture of fine powders of amorphous boron and ammonium nitrate
is used in the experiments. A comparative quantitative X-ray powder diffraction analysis of various segments of the coating
is performed. The values of the unit cell parameters indicate the formation of complex phases. The dynamics of the results
of the X-ray study with the cone angle of the liner decreasing from 45 to 20° is demonstrated.
