研制了水热KNbO_3厚膜超高强度高频超声换能器。用厚度振动法测量了KNbO_3厚膜表面的振动速度。振速幅值在2.5m/S以上。并在脱气水中以共振频率测量了超声换能器样机的辐射声压。辐射超声大于或等于4 Mpa。
Very high intensity and high frequency ultrasonic transducer using hydrothermal KNbO3thick film was developed. The vibration velocity of surface of KNbO3thick film was measured with thickness vibration mode. The amplitude of vibration velocity was 2.5m/s or over. And the radiation sound-pressure from the prototype ultrasonic transducer was measured at resonance frequency in degassed water. The radiation ultrasound was 4MPa or over.
