| Résumé | Thick (>40µm) ceramic films as piezoelectric ultrasonic transducers (UTs) have been successfully deposited on metallic substrates by a spray technique. In the film fabrication a composite consisting of piezoelectric powders well mixed with solution of high dielectric constant is directly sprayed onto the substrate. It is then dried, fired or annealed by heat. Multiple coating is used to achieve desired film thicknesses. A corona poling is utilized to achieve the piezoelectricity of the film. The top electrode is accomplished by painting, spray coating, or vacuum evaporation of appropriate electrode materials. All fabrication processes can be carried out on-site and by handheld devices. Integrated ultrasonic longitudinal, shear, and plate wave transducers have been made. These transducers have been tested and operated at 350°C. |
