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 the intelligent BaTiO3 coating. The preparation method comprises the following steps of forming a BaTiO3 ceramic coating on the surface of a substrate; and carrying out a polarization treatment on the BaTiO3 ceramic coating so that the BaTiO3 ceramic coating is of a piezoelectric effect. The obtained intelligent BaTiO3 coating has functions of a piezoelectric sensor and the self abrasion state of the intelligent BaTiO3 coating is monitored and fed back in real time so that a sensor does not need to be adhered. Compared with a sensor and a substrate combined by adhesion in the prior art, the preparation method of the intelligent BaTiO3 coating, disclosed by the invention, can prevent a problem of poor adhesion between the sensor and the substrate.

Description

technical field [0001] The present invention relates to the technical field of surface coating, more specifically, to a kind of BaTiO 3 Preparation method of smart coating and BaTiO 3 Smart coating. Background technique [0002] In order to improve the wear resistance of the surface of the part, a coating is usually prepared on the surface of the part. When the coating on the surface of existing parts is in service, if the dynamic damage cannot be sensed, the wear state of the coating cannot be controlled. [0003] The current coating fatigue wear tests mostly use the changes of vibration, friction coefficient, temperature and other factors as the judgment basis for evaluating the coating wear state. When the actual value of the selected judgment factor exceeds the preset threshold value, it means that the coating has failed, and then the fracture analysis of the failed part is carried out, and the failure mechanism is deduced reversely through experience or classical the...
