The microstructure of YBa/sub 2/Cu/sub 3/O/sub 7-δ/ films and yttria stabilised zirconia buffer layers deposited on inclined Hastelloy substrates

INCLINED SUBSTRATE DEPOSITED CeO2 FILMS BY ELECTRON BEAM EVAPORATION ON RANDOMLY ORIENTED METALLIC SUBSTRATE

“…As already observed for MgO and YSZ films deposited by ISD technique [7,8], Ce02 texture is improved with film thickness. This suggests an evolutive selection of film orientation [10].…”

“…Up to now, typically used oxides materials for ISD deposition were Y 2 0 3 stabilisedZr0 2 (YSZ) and MgO [7,8,9]. The ISD YSZ shows a texture with the (001) planes parallel to the substrate surface, whereas the [001] axis of ISD MgO is tilted from the substrate normal.…”

Room temperature growth of biaxially aligned yttria-stabilized zirconia films on glass substrates by pulsed-laser deposition

“…Thus, good quality polycrystalline YSZ films can be deposited by conventional PLD without IBAD. Though no tilted columnar growth can be confirmed in our experiments, the off-normal plume for deposition due to the inclinedsubstrate may still be the drive of the formation of the in-plane orientation [14].…”

“…This also explains why the films deposited in argon show the pressure-insensitive broad (200) peaks. Although the set-up used for deposition in this paper is a kind of inclined-substrate system [23], and the samples were cut along the direction of the arriving species for cross-section observation, tilted columnar grain growth, as mentioned in [13,14,20], was hardly seen.…”

Pulsed laser deposition of the yttria-stabilized zirconia films

“…In these applications, mostly dense, smooth and uniform surface and superior thermo-mechanical properties of the films are desirable to enhance the lifetime of components operated in extreme environments. It is reported that the pulsed laser deposition (PLD) technique generally meets these requirements by providing superior properties of the deposited YSZ films [14][15][16][17][18][19]. Therefore, study of various properties of the YSZ film produced by PLD is necessary for potential applications of the YSZ film in the hard and protective coating area.…”
