Abstract
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.
