Formation of a Specific Layer on the Surface of a Metallic Target Interacting with a Shaped-Charge Jet of Boron-Containing Liners

摘要

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/mm~2.A conical liner with a cone angle of 20 deg 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 deg is demonstrated.
