摘要： The invention relates to a green body, a piezoelectric component (10) and a method for the production of a piezoelectric component (10) in the form of a multilayer structure having at least one piezoelectric ceramic layer (11) and at least one electrode layer (12) connected to the piezoelectric ceramic layer (11). A green body is initially produced, wherein at least one electrode layer (12) is placed on at least one piezoelectric green ceramic layer. The resulting stack (16) for producing the piezoelectric component (10) is then subjected to at least one additional finishing step, for instance a sintering step. In order to produce piezoelectric components (10) with a long service life and high reliability, the at least one piezoelectric ceramic layer (11) is not configured as an individual layer but in the form of a first ceramic partial layer (13) and at least a second ceramic partial layer (14, 15). The ceramic partial layers (13, 14, 15) advantageously have a thickness which is smaller than the thickness of the piezoelectric ceramic layer (11) after carrying out the finishing step. In the production of the green body, a first green ceramic partial layer that can carry an electrode layer (12) is advantageously placed on at least one second green ceramic partial layer that does not carry an electrode layer.

摘要： PROBLEM TO BE SOLVED: To retain a further improved electrical connection as well as a higher number of cycles and operating life. SOLUTION: Conductive contact pieces 20, 21 mechanically and conductively couple with metal coated strips 28, 29 of the surfaces 12, 13 of an actuator body 11 via a brazed portion 27. The expansion of contact pieces 20, 21 provides adaptation means 24, 25 for adapting to the sizes of extension and shrinkage of the actuator body 11. These adaptation means 24, 25 are deformable materials, comprise laminated matters of a plurality of wire materials and a plurality of highly elastic coats, and contact pieces 20, 21 hardly create mechanical stresses in the expansion and shrinkage of the actuator body 11. As a result of this, electrical contact connection of the piezoactuator can be positively guaranteed, and is superior providing high reliability and a high number of cycles.

摘要： The external contact manufacturing method uses screen printing for forming a metallisation layer on at least surface regions of the electroceramic component. An initial screen printing process is used for application of a metallisation paste having an optimum adhesion to the electroceramic component, with a thickness of between 2 and 10 microns, before application of a metallisation paste with goog sodering characteristics.
