The coatings were evaluated for their corrosion resistance in 3.5 % NaCl and neutron activation. The effect of adding Si and Nb to the quaternary TiZrCN system was also investigated. The results showed that the addition of Si (∼4.64 at.%) to the matrix of TiZrCN improved their electrochemical properties in NaCl solution, the protective efficiency was 92%, while the Nb addition (∼5.5 at%) lead to the decrease in corrosion resistance by 1.39 times comparing with TiZrCN. Furthermore, after fast neutron irradiation at a nominal power of 1450 kW, none of the coatings were activated, indicating good radiation resistance. It was determined from the structural analysis that the Ti6Al4V substrate before corrosion consists of hexagonal and cubic space groups with different lattice parameters. By adding Si and Nb, a small amount of ZrO2 and Si3N4 was detected along with the main phases in the TiZrCN structure.}, journal={NUCLEAR MATERIALS AND ENERGY}, author={Vladescu, A. and Mirzayev, M.

The microstructure of the titanium carbide nano powders after irradiation was examined using X-ray diffraction, Raman spectroscopy, and FTIR spectroscopic analysis methods. The X-ray diffraction analysis revealed that no significant phase transition or amorphization occurred in the TiC nano powders exposed to fast neutrons. More sensitive results obtained from the FTIR analysis showed that the water molecules absorbed on the material surface were disintegrated under the influence of fast neutrons. Exceptional structural stability to neutron irradiation of titanium carbide without amorphization was also observed by morphological analysis via transmission electron microscopy (TEM) and selected area electron diffraction (SEAD).}, journal={VACUUM}, author={Popov, E. and Slavov, L. and Demir, E. and Abdurakhimov, B.
