METHOD OF MANUFACTURING OF ANHYSTERETIC ACTUATOR WITH LINEAR PIEZOELECTRICAL CHARACTERISTIC |
摘要 |
FIELD: electricity.SUBSTANCE: method contains connection by plains of single-domain monocrystal plates of lithium niobate or lithium tantalat such that directions of spontaneous polarisation in plates will be opposite to each other. For this preliminary polished connected surfaces of plates out of lithium niobate or lithium tantalat are cleaned such that to ensure their hydrophilic properties. Then the plates are connected by the planes, plates are compressed until disappearance of the interference rings, then they are annealed to create double-domain plate. To the opposite surfaces of the plates the electrodes are applied out of the material resistant to high temperatures.EFFECT: possibility to ensure anhysteretic actuators with linear characteristic operable in wide range of temperatures, improved produceability.2 cl, 5 dwg |
