Popis: In this work, stability of titanium and zirconium nitride coatings deposited on steel and molybdenum was studied. The phase composition of nitride coatings was studied by X-ray method before and after emission testing in the nanosecond range of pulses. It was noted that before the testing, the titanium nitride coating was a successive alternation of α-Ti, Ti2N, and TiN layers. After the testing, titanium was transformed into the β-phase (bcc), nitrogen was partially evaporated, and a new phase, presumably Ti3N, with a tetragonal lattice was formed in a significant content. The Zr-N coating, obtained in the form of zirconium mono-nitride, showed structural stability during testing.
