Abstract

The invention relates to the technical field of functional ceramics, in particular to a preparation method of a PZT ceramic coating. The preparation method comprises the steps that (1), steel is selected for a sample piece, the sample piece is placed into an acetone beaker, the sample piece is taken out after ultrasound is performed, and sand blasting processing is performed with brown aluminum oxide; (2), PZT powder is dispersed in distilled water, suspension liquid A is obtained and oscillated with an ultrasonic generator; (3), silica sol is added into the suspension liquid A, and the mixture is oscillated in the ultrasonic generator; (4), a high-temperature electric furnace is heated in advance, the sample piece obtained after sand blasting processing is taken out to be placed into the electric furnace, and the heated sample piece is soaked in suspension liquid B and oscillated in the ultrasonic generator; (5), the sample piece obtained after ultrasound continues to be placed into the high-temperature electric furnace, the heated sample piece is soaked in the suspension liquid B, the soaked sample piece is taken out and oscillated in the ultrasonic generator, and the step is repeated till the required coating thickness is reached. The PZT ceramic coating prepared through the preparation method has the advantages that the process is simple, the cost is low and product performance is excellent.

Description

technical field [0001] The invention relates to the technical field of electronic ceramics, in particular to a preparation method of a PZT ceramic coating. Background technique [0002] Since people discovered the piezoelectric effect, piezoelectric materials have been developed for more than 130 years. During this period, people's research and exploration of piezoelectric materials have never stopped, so piezoelectric materials have developed rapidly. It is widely used in important aspects such as electronics, communication, machinery, military affairs, and confidential control, especially in the fields of information detection, conversion, processing, and storage. Due to its simple production process and good performance, piezoelectric ceramics have become an important branch of piezoelectric materials and an important research direction of functional materials. [0003] Lead zirconate titanate (PZT) is a piezoelectric ceramic material, which is widely used in piezoelectr...
