Effect Of Irradiation With Low-Energy Alpha Particles On The Structural-Phase State Of Coatings Of Triple Nitride Systems Based On Titanium And Vanadium On Steel

The paper presents the results of studies of the effect of alpha-particle irradiation on the structural-phase composition of nitride coatings CrTiN, MoTiN and NbTiN on the surface of a steel substrate. The coatings were formed by vacuum-arc condensation in a gas medium with N₂ using ion bombardment with the use of Ti, Cr, and Mo cathodes. In addition, coatings in a N₂ gas medium on a steel substrate were produced by magnetron sputtering from Ti and Nb metals. Experimental data and the analysis of state diagrams of ternary systems of nitrides based on titanium and vanadium with transition metals of IVA-VIA groups have allowed deriving criteria for choosing materials for production of nitride coatings with a fairly high radiation stability.
