Electrical properties of UV-irradiated thick film piezo-sensors on superalloy IN718 using photochemical metal organic deposition
Abstract
Lead zirconate-titanate thick films of perovskite structure Pb(Zr<sub>0.52</sub>Ti<sub>0.48</sub>)O<sub>3</sub> were fabricated on the curved surface of IN718 superalloy substrate using photochemical metal organic deposition technique. The films were heated at 200 °C, irradiated by UV lamp (365 nm, 6 W) for 10 min, pyrolyzed at 400 °C, and subsequently annealed at 700 °C for 1 h after successive multi-step coating with 10 wt.% excess PbO. Fairly smooth, dense, and crack-free polycrystalline thick films of Au/PZT/Au structure were deposited on IN718. The films were characterized to investigate the effect of photochemical deposition process and substrate on the crystalline, morphological, dielectric, ferroelectric and piezoelectric properties. Remanent polarization (<i>P<sub>r</sub></i> = 20.2 μC/cm<sup>2</sup>), coercive field (<i>E<sub>c</sub></i> = − 10 kV/cm), permittivity (<i>ε<sub>r</sub> </i>= 324@1 kHz), dielectric loss (<i>tanδ</i> ≈ 3%), and piezoelectric charge coefficient (<i>d<sub>33</sub></i> = 113.4 pm/V) of the PZT thick film transducers were measured and interpreted as regards domain wall motions. Consequently, the photochemical grown lead zirconate-titanate thick film on the superalloy substrate IN718 was confirmed to be consistent to structural health monitoring due to its acceptable electrical response.
