【摘要】：分别采用Sn-40Pb,Sn-3.5Ag和Sn-52In钎料对PZT8压电陶瓷和铜定子弹性体进行了钎焊试验,对比分析了3种钎料钎焊定子的振动性能以及钎焊压力对振动性能的影响.结果表明,采用Sn-52In钎料,配合松香类有机钎剂,在峰值温度141℃,回流时间116 s,钎焊压力38.26~114.78 k Pa内的工艺条件下,钎焊形成定子的振动性能最好;在电压峰峰值80 V的激励下,钎焊定子的振幅为2.5μm,达到了胶粘定子的振动水平;钎焊接头的抗剪强度达到6.88 MPa,超过了超声电机定子对力学性能(≥5 MPa)应用的要求,有望解决胶粘工艺胶接层老化的问题,从而提高超声电机的使用寿命.
[Abstract]:The brazing tests of PZT8 piezoelectric ceramics and copper stator elastomers were carried out by using Sn-40Pb,Sn-3.5Ag and Sn-52In solders, respectively. The vibration properties of three kinds of brazing stator and the effect of brazing pressure on the vibration properties were compared and analyzed. The results show that the vibration properties of the stator formed by brazing are the best under the conditions of Sn-52In solder, rosin organic flux, peak temperature 141 鈩，
