Abstract

We know that the piezoelectric constant d, the dielectric constant, and the electric-mechanical coupling coefficient affect the output for piezoelectric ceramics used in ultrasonic welders. Therefore, in this study, the characteristics of ceramics according to the changes of additives to the components of PZT-PMN-PZW were examined. When the addition amount of $MnO_2$ was 2 wt%, the most excellent properties were shown, which suggested the applicability as a material for fusion welding.

압전 상수 d의 값과 유전 상수 및 전기 기계적 결합 계수가 초음파 용접기에 사용되는 압전 세라믹의 출력에 영향을 주고 있습니다. 따라서 본 연구에서는 초음파 융착기의 진동 소자로 사용할 압전 세라믹 PZT-PMN-PZW의 $MnO_2$ 첨가량에 따른 세라믹의 특성을 조사 하였으며, $MnO_2$의 첨가량을 2 wt.%로 한 경우, 가장 우수한 특성을 얻을 수 있었으며, 이는 초음파 융착기용 진동소자로서의 적용 가능성을 시사하였다.
