摘要： The invention provides a lead titanate coating and a preparing method thereof. According to the method, mixed powder is sprayed on the surface of a matrix, and through polarization, the lead titanate coating is acquired. The mixed powder comprises PbTiO3 powder, PbO powder and Al powder. Lead titanate (PbTiO3) is a kind of ferroelectric material, and can be used for preparing a piezoelectric sensor. Besides, the PbO powder and the Al powder are added, so that the piezoelectric property of the lead titanate coating can be improved. Since the lead titanate coating prepared by the present invention can be combined with the matrix closely and the intensity of piezoelectric signal is high, it can be widely applied to mechanical parts, such as a piston ring, a cylinder, a gear, and the like, to dynamically monitor the service situations of the parts better.

摘要： The present invention disclose a smart coating comprising a substrate, optionally a first insulating layer, a plurality of first sensing units, a second insulating layer, a plurality of second sensing units and optionally a wear-resistant layer, wherein the plurality of first sensing units and the plurality of second sensing units have piezoelectric effect. The smart coating can provide real-time monitoring and feedback of the worn state of the surface of a part while eliminating the need to adhere a senor. Compared with the existing sensors and substrates bound by adhesion, the smart coating provided in the present application can avoid poor adhesion between the sensor and substrate. Furthermore, damaged positions can be located precisely so as to provide more and more accurate information regarding worn state of the part surface, which is in favor of monitoring and post-stage analysis on the worn state of the surface of the part.
