METHOD FOR JOINING A CERAMIC FRICTION ELEMENT TO A PIEZOCERAMIC ELEMENT
The invention relates to a method for joining a ceramic friction element (11) to a piezoelectric element (1), comprising, among other things, the following steps: pressing (14) a joining surface (10) of the friction element and a contact surface (9) of the piezoelectric element against each other with a low-melting glass mass (12) arranged therebetween and maintaining the pressing force for all subsequent steps; heating (17) the piezoelectric element and the friction element to a defined temperature above the Curie point of the piezoceramic material of the piezoelectric element and above the melting point of the low-melting glass mass; thereafter, while maintaining the temperature, applying an electric polarization voltage Up to electrodes of the piezoelectric element; removing the polarization voltage after the Curie point has been fallen below; and cooling the piezoelectric element and the friction element to room temperature without an electric voltage being applied to the electrodes.
