  text: Der Verbau von Sheet Moulding Compounds im automobilen Außenhautbereich führt
    in der industriellen Praxis regelmäßig zu abnehmenden Direktläuferquoten in der
    Technologie Oberfläche, denn neben bekannten Lackierfehlern ergeben sich auch
    werkstoff-spezifische Oberflächendefekte, welche einen Bauteilwechsel bedingen.
    Die hier vorliegende Arbeit soll einen aktiven Beitrag zur Reduzierung von Ausschuss
    und Nacharbeit entlang der Lackierprozesskette leisten. Zu Beginn werden die erfolgskritischen
    Oberflächendefekte identifiziert und die zugehörigen Fehlerursachen ermittelt,
    ehe anschließend die Entwicklung der Fehlstellengrößen in Folge der Temperaturbelastung
    während der Trocknerdurchfahrten untersucht wird. Ferner soll die Auswirkung einer
    zusätzlich applizierten Oberflächengrundierung auf die Fehlerhäufigkeit sowie
    die Oberflächengüte im decklackierten Zustand geprüft werden. Als weitere Möglichkeit
    zur Problemlösung wird eine in den Prozessablauf integrierte Qualitätskontrolle
    gesehen, weshalb in dieser Arbeit ebenso die Eignung bekannter zerstörungsfreier
    Prüfmethoden für die präventive Fehlererkennung überprüft und ein zweistufiges
    Prüfkonzept erarbeitet wird. Das Aufzeigen möglicher Handlungsalternativen sowie
    die kostentechnische Gegenüberstellung der verschiedenen Anbauvarianten runden
    die Arbeit ab.

  text: (K,Na)NbO3 ceramics have attracted much attention as lead-free piezoelectric
    materials with high piezoelectric properties. High-quality (K,Na)NbO3 ceramics
    can be sintered using KNbO3 and NaNbO3 powders synthesized by a hydrothermal method.
    In this study, to enhance the quality factor of the ceramics, high-power ultrasonic
    irradiation was employed during the hydrothermal method, which led to a reduction
    in the particle size of the resultant powders.

  text: Hydrothermal method enables to synthesize high quality piezoelectric materials.
    To shorten the reaction time and to get higher quality materials, we propose an
    ultrasonic irradiation to the solution during the hydrothermal method. We named
    it ultrasonic assisted hydrothermal method (UAHTM). We have synthesized lead-free
    piezoelectric material and PZT thin film and the effect of UAHTM have been confirmed.
    In this study, we tried to improve UAHTM. First, to generate powerful and stable
    ultrasonic irradiation at high temperature on UAHTM, we developed a new transducer
    using LiNbO3 single crystal. Second, to prevent contamination to the materials,
    A Teflon cover on the tip of transducer was attached.

  text: 'A hydrothermal method utilizes a crystallization process in the solution
    so that the pure and high-quality powders can be realized. Sintering from the
    hydrothermal KNbO3 and NaNbO3 powders, a high-dense lead-free piezoelectric (K,Na)NbO3
    ceramics could be obtained (density: 98.8\%). Concerning about the g33 constant,
    high value as large as commercial PZT ceramics was measured. Therefore, the hydrothermal
    (K,Na)NbO3 ceramics is usable for the sensors and the energy harvesting devices.
    To demonstrate the (K,Na)NbO3 ceramics, a hydrophone sensor was fabricated and
    evaluated.'
