Piezoceramic multilayer actuator and method of manufacturing a piezoceramic multilayer actuator
摘要：
A piezoceramic multilayer actuator (10) has a plurality of piezoceramic layers (12) and a security layer (20) disposed between two piezoceramic layers (12). The piezoceramic layers (12) have a piezoceramic first material sintered at a sintering temperature. The security layer (20) has a second material (32) and particles (30) at least partially embedded in the second material (32). The particles (30) have a third material different from the first material and different from the second material (32). An adhesion between the third material and the first material is weaker than an adhesion between the second material (32) and the first material.
摘要（中）：

压电陶瓷多层致动器（10）具有多个压电陶瓷层（12）和设置在两个压电陶瓷层（12）之间的安全层（20）。 压电陶瓷层（12）具有在烧结温度下烧结的压电陶瓷第一材料。 安全层（20）具有至少部分地嵌入第二材料（32）中的第二材料（32）和颗粒（30）。 颗粒（30）具有不同于第一材料并且不同于第二材料（32）的第三材料。 第三材料和第一材料之间的粘附力弱于第二材料（32）和第一材料之间的粘合力。
