On the Radiation Hardness of Thermostabilizing BaTiZrO 3 Coatings in situ Deposited by the Detonation Method

摘要

The radiation hardness of three types of BaTiZrO~(3)coatings obtained by synthesis from the powder mixtures BaTiO~(3)+ ZrO~(3), BaCO~(3)+ TiO~(2)+ ZrO~(3)(micron size), and BaCO~(3)+ TiO~(2)+ ZrO~(3)(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 × 10_(16)cm_(–2)is established in measurements of the diffuse reflection spectra in vacuum at the place of irradiation (in situ).
