Problems solved by technology

[0006] However, due to the complex structure of some mechanical equipment or the harsh working environment, the combination between the piezoelectric sensor and the equipment is poor, resulting in poor detection accuracy of the piezoelectric sensor and even the problem of falling off.

Abstract

The embodiment of the invention discloses a preparation method of a PbTiO3 intelligent coating, which comprises the following steps: forming a prime coating layer on a substrate surface, forming a PbTiO3 sensing layer on the prime coating layer surface, and performing polarization treatment of the PbTiO3 sensing layer to provide the PbTiO3 sensing layer with piezoelectric effect. The obtained PbTiO3 intelligent coating has the function of a piezoelectric sensor, and can realize real-time monitoring and feedback of the abrasion states of the substrate surface and the PbTiO3 intelligent coating itself, and thus no sensor is necessary to be pasted. In addition, the prime coating layer is disposed between the PbTiO3 sensing layer and the substrate, which provides very strong bonding degree between the PbTiO3 sensing layer and the substrate. Compared with current sensors and substrates which are bonded through pasting, the preparation method of the PbTiO3 intelligent coating provided by the invention can avoid the problem of poor bonding degree between sensors and substrates.

Description

technical field [0001] The invention relates to the technical field of surface coatings, in particular to a preparation method of a PbTiO3 intelligent coating and the PbTiO3 intelligent coating. Background technique [0002] When the existing part surface is in service, if the dynamic damage cannot be sensed, the wear state of the part surface cannot be controlled. [0003] The current fatigue and wear tests on the surface of parts mostly use the changes of vibration, friction coefficient, temperature and other factors as the judgment basis for evaluating the wear state of the part surface. When the actual value of the selected judgment factor exceeds the preset threshold value, it means that the surface of the part has failed, and then the fracture analysis of the failed part is carried out, and the failure mechanism is reversely deduced through experience or classical theory. However, this kind of failure behavior and mechanism research based on "post-judgment" cannot jud...
