“…Xenon thermal migration behaviour in TiN was studied in a previous work and segregation into gas bubbles was shown as a result of xenon low solubility [25]. For iodine, the formation of bubbles several nanometers in size has been demonstrated within UO 2 single crystals that had been implanted with 40 keV 127 I ions at a fluence of 10 16 cm À2 and annealed at 1500°C [27].…”

“…Most of the existing studies have been focused on the behaviour of FP, especially rare gases Xe and Kr [22][23][24], in oxide nuclear fuel in the past four decades and, unfortunately, very few in nitride compounds [25,26]. Xenon thermal migration behaviour in TiN was studied in a previous work and segregation into gas bubbles was shown as a result of xenon low solubility [25].…”

“…These compounds combine ceramics and metal properties and have increased hardness, wear resistant and corrosion stability, thermal stability [6][7][8]. The transition metals TiCrN, TiZrN, TiMoN and other nitrides coatings are considered to be perspective as protective coatings [9,10]. However these covering properties stability problem under the irradiation influence is not sufficiently explored [9][10][11][12].…”

Abstract.The low-energy alpha particles irradiation impact on structural phase composition and 321S31 steel surface TiCrN and TiMoN coatings morphology have been summarized. The samples irradiation has been carried out in the DTs-60 (the Dubna cyclotron) heavy-ion accelerator by the 4 He +2 low-energy ions (40 keV) into a 1.0·10 17 ion/cm 2 fluence. It has been established thatthe 321S31 steel alpha particles implantation having energy of 40 keV results in the austenite initial γ-structurepartial transfer, stimulated by the irradiation, to the martensiteα-structure. The low-energy alpha particles irradiation within the fluencies range from 10 16 to 10 17 ion/cm 2 for the TiCrN and TiMoN coatings formed by the ionic bombardment condensation method doesn't result in the phase transfers with a coating crystal lattice type change.

Nitride coatings have already been examined as a perspective for covering of surface cladding of gas-cooled fast reactors (GFR) [8] and it makes current studies of their radiation resistance. As follows from our investigations, the best results were found for the multicomponent composite coatings based on the solid solutions of nitrides of several transition metals (Ti-Cr-N, Ti-Zr-N, Ti-Mo-N and others) [9,10].…”

Effects of Irradiation with Low-Energy and High-Energy Krypton Ions on the Structure of TiCrN Coatings

The results of surface structure investigations of TiCrN coating on carbon steel after irradiation by highand low energy krypton ions and successive two-hour vacuum annealing are reported in the present publication. Specimens with the TiCrN coatings of the 50 ÷ 100 nm thickness were formed by vacuum arc deposition techniques. The prepared specimens were irradiated by low energy (280 keV) and high energy (125 MeV) krypton ions. Study of surface structure was done by scanning electron microscopy and atomic force microscopy. X-ray diffraction and the Rutherford backscattering spectrometry were applied for determination of structure and coating thickness. After irradiation by high energy Kr ions there appear convexities of spherical shape with dimensions 10 ÷ 30 nm on the surface of the coating. Subsequent two-hour vacuum annealing led to decrease of convexities dimensions. Irradiation by low-energy Kr ions does not lead to significant changes in the structure of the coating surface. Only traces of surface sputtering are found. Explanation of the observed surface damage is proposed. Convexities are the traces of ions passing through coating and appear due to structural reconstruction at energy release along a trajectory of ions braking. As the projective range of high energy Kr ions exceeds coating thickness, then damage of structures is generated in the substrate and convexities are the traces of undersurface damages.
