Surface of a titanium target after interaction with shaped-charge jet particles

Coatings containing $\beta$-WC$_{1-x}$ and W$_2$C$_{1-x}$ tungsten carbides were produced on titanium targets by a shaped-charge explosion. The experiment used conical liners with a cone angle of 30$^\circ$ manufactured from a mixture of fine powders of tungsten, graphite, and ammonium nitrate. A comparative quantitative x-ray analysis of the top and bottom layers of the coating was performed. For the phase $\beta$-WC$_{1-x}$ in the bottom layer, the value of the cubic unit cell parameter falls outside the range known in the literature. Microhardness in different segments of the target was studied.
