On the Radiation Hardness of Thermostabilizing BaTiZrO3 Coatings in situ Deposited by the Detonation Method

Resumo

The radiation hardness of three types of BaTiZrO₃ coatings obtained by synthesis from the powder mixtures BaTiO₃ + ZrO₃, BaCO₃ + TiO₂ + ZrO₃ (micron size), and BaCO₃ + TiO₂ + ZrO₃ (nanopowder) deposited by the detonation method on metal substrates is investigated. The high radiation resistance of all types of coatings to the action of electrons with an energy of 30 keV and a fluence of up to 4 × 10¹⁶ cm^–2 is established in measurements of the diffuse reflection spectra in vacuum at the place of irradiation (in situ).
