The invention discloses a preparation method of a high-corrosion-resistance composite piezoelectric ceramic material. The preparation method comprises the following steps: (1) component weighing: weighing the components according to a stoichiometric ratio of Ba<1-x>MgTi<1-2y>SbInO3, with x being 0.5-3 mol%, and y being 0.2-3 mol%. (2) preliminary molding: mixing the raw materials, and performing ball milling, drying, granulation, extrusion molding, binder discharging, sintering and other processes to obtain piezoelectric ceramic; and (3) polarization treatment: respectively carrying out tin soldering and solver electrode magnetron sputtering on the upper surface and the lower surface of the primarily-formed piezoelectric ceramic to finally obtain the high-corrosion-resistance composite piezoelectric ceramic material. The preparation method is simple in step, BT-based ceramic is doped in a soft and hard mode, the piezoelectric constant d33 is guaranteed, and the mechanical quality factor Qm and the electromechanical coupling coefficient Kp are improved. The invention also provides the high-corrosion-resistance composite piezoelectric ceramic material prepared by the method.
本发明公开了一种耐高腐蚀的复合压电陶瓷材料的制备方法包括以下步骤：(1)称量组分：按化学计量比Ba1‑xMgxTi1‑2ySbyInyO3进行称量；其中x为0.5‑3mol％，y为0.2‑3mol％。(2)初步成型：将各组分所述原料混合后经过球磨、烘干、造粒、挤压成型、排胶、烧结等工艺处理得到压电陶瓷；(3)极化处理：将初步成型的压电陶瓷上下表面分别锡焊和磁控溅射银电极，最终得到所述耐高腐蚀的复合压电陶瓷材料。本发明的制备方法步骤简单，通过软硬兼施的方式对BT基陶瓷掺杂，既保证了压电常数d33，又提升了机械品质因数Qm和机电耦合系数Kp。本发明还提供一种该方法制备的耐高腐蚀的复合压电陶瓷材料。
