Ultrasonic diffraction and scattering characteristics:When the ultrasonic wave propagates through the medium, it encounters a heterogeneous interface (such as a defect). According to the huygens principle, a diffraction phenomenon occurs at the edge thereof, and a newly excited diffraction wave is g

The thickness of ultrasonic thickness measurement gauge has become an important part of the processing industry and surface engineering quality inspection, and it is a necessary means for products to achieve superior quality standards. In order to internationalize the products, China's export commod

1.General measurementPerforming the thickness measurement gauge is twice with the probe at one point. In the two measurements, the split faces of the probes should be 90° each other, and the smaller value is the thickness of the workpiece to be tested.2.30mm multi-point measurement method: When the

Several methods in measurement1—Single measurement method: measurement at one point2—Double measurement method: Perform two measurements with a probe at one point. The probe crosstalk spacers should be perpendicular to each other in both measurements. Selecting the minimum value in the reading as th

what is the use of ultrasond sensorResearches on the microstructure of plasma sprayed BaTiO3 coatings have recently made new progress. The microstructures of BaTiO3 coatings, the cross-sections of plasma BaTiO3 coatings and the microstructures under plasma spark plasma sintering can be seen. Part of
