Piezoelectric ceramic surface metallization method
The invention relates to the technical field of ceramic metallization, in particular to a piezoelectric ceramic surface metallization method, which comprises the following steps: firstly, preparing a tape casting slurry containing ferrite, enabling the tape casting slurry to pass through a tape casting machine to obtain a tape casting sheet, carrying out lamination isostatic pressing on the tape casting sheet and a piezoelectric ceramic body to obtain a biscuit, heating and degreasing the biscuit in a first section, and then carrying out hot pressing on the biscuit to obtain the piezoelectric ceramic surface metallization. The preparation method comprises the following steps: firstly, preparing a metallized layer on the surface of the composite ceramic chip, then heating to 950-1050 DEG C in a second stage, sintering for 1-5 hours to obtain the composite ceramic chip, and finally, forming a nickel-copper alloy layer and a silver layer on the surface of the composite ceramic chip in a magnetron sputtering manner. The prepared piezoelectric ceramic has excellent piezoelectric property, and the bonding property between the metallized layer and a piezoelectric ceramic matrix is good.
本发明涉及陶瓷金属化技术领域，具体为一种压电陶瓷表面金属化方法，先制备含铁氧体的流延浆料，流延浆料通过流延机得到流延片材，将流延片材与压电陶瓷坯体叠层等静压后得到素坯，将素坯先一段升温脱脂后，再二段升温至950‑1050℃烧结1‑5h得到复合陶瓷片，最后通过磁控溅射的方式在复合陶瓷片表面形成镍铜合金层和银层即可，本发明所制备的压电陶瓷具有优异的压电性能，而且金属化层与压电陶瓷基体间的结合性能良好。
