摘要
Strontium zirconate SrZrO3 is a multifunctional material studied in literature as a luminescent material, proton-conductor, thermal barrier coating, and dielectric ceramics. In our study this material was sprayed by a high feed-rate water-stabilized plasma torch WSP 500 at its standard electric power 150 kW. The as-deposited coatings exhibited lamellar microstructure with relatively high porosity over 13%. Archimedean (water immersion) specific weight was 4.54 g/cm(3). Annealing was done in air at 1350 degrees C. Annealed coating exhibited an interesting response to UV light, including after-glow luminescence. After excitation by 225nm light the sample exhibited after-glow exponential luminescence decay with 5 s characteristic lifetime. Diffused reflectance of the coatings was measured as well. The infrared reflectance is slightly lower after annealing, whereas in the ultraviolet band it is higher. (C) 2018 SECV. Published by Elsevier Espana, S.L.U.
