| Popis: | Nanostructured yttria-stabilized hafnia (YSH) coatings were grown on α-Al 2 O 3 substrates with variable coating thickness in a wide range of ~ 50 nm to 1 μm. Microstructure and thermal oxidation behavior of the grown YSH coatings were studied employing X-ray diffraction (XRD), Rutherford backscattering spectrometry (RBS), scanning electron microscopy (SEM) and isothermal furnace oxidation testing. The effect of coating thickness on the crystal structure, surface/interface morphology and thermal oxidation was investigated. X-ray diffraction analyses revealed the formation of monoclinic phase for relatively thin coatings ( |
