Study on Defect Location Based on Zirconia Ceramics
Zirconia ceramic materials have excellent physical and chemical effects,because of the small defects may occur in the process of processing,so it is necessary to carry out defect detection.In this paper,two locating methods are discussed for the defect location of zirconia ceramic sheet.One is to locate the defect with the difference of the probe distance and its nonlinear coefficient during the experiment.Another positioning method is to locate the ultrasonic wave through the propagation speed in the material,calculate its excitation signal and the time of receiving the signal,so as to locate it.The results show that both of these algorithms can determine the location of defects well.
