В данной работе представлены экспериментальные результаты исследования структурных и фазовых изменений нитрид-титановых (TiN) покрытий при термическом и электронном облучении. Непрерывное электронное облучение покрытых образцов проводили на ускорителе ЭЛВ-4. Установлено, что электронное облучение с энергией электронов 1,3 МэВ и интегральной дозой облучения 0.52·1019 e−/см2 приводит к увеличению микротвердости покрытий TiN на 20%. Установлено, что основным фактором увеличения микротвердости покрытия после электронного облучения в вышеуказанных режимах является образование новых фаз, в частности интерметаллида Co2Ti.

This work presents the experimental results of structural and phase changes research study in TiN coatings under thermal and electron irradiation. Continuous electron irradiation of coated samples was performed on the ELV-4 accelerator. It was determined that electron irradiation with an electron energy of 1.3 MeV and an integral irradiation dose of 0.52·1019 e−/cm2 leads to an increase in the microhardness of TiN coatings by 20%. It has been established that the main factor in increasing the microhardness of the coating after electron irradiation in the above regimes is the formation of new phases, in particular the intermetallide of Co2Ti.
