Background
The nondestructive testing is a technology for inspecting and testing the structure, the property, the state and the type, the property, the quantity, the shape, the position, the size, the distribution and the change of the defect inside and on the surface of a workpiece by taking a physical or chemical method as a means and by means of modern technology and equipment on the premise of not damaging or not influencing the service performance of the tested object and not damaging the internal tissue of the tested object and utilizing the change of the reaction of heat, sound, light, electricity, magnetism and the like caused by the abnormal structure or the existence of the defect inside the material.
Ultrasonic testing is one of the methods of industrial non-destructive testing. When the ultrasonic wave enters an object and meets a defect, a part of the sound wave can be reflected, and the receiver can analyze the reflected wave, so that the defect can be measured abnormally and accurately, the position and the size of the internal defect can be displayed, the thickness of a material can be measured, and the like. An ultrasonic probe is a device that transmits and receives ultrasonic waves during ultrasonic testing. The performance of the probe directly affects the characteristics of the ultrasonic waves and the detection performance of the ultrasonic waves. The probe used in ultrasonic detection is a transducer which realizes the conversion of electric energy and sound energy by utilizing the piezoelectric effect of materials. The key component of the probe is a wafer, which is a single crystal or polycrystalline wafer with piezoelectric effect, and functions to convert electric energy and acoustic energy into each other.
The coupling agent is used for high-frequency ultrasonic energy transfer between the probe and the material to be detected. The couplant is used for removing air between the probe and the object to be detected, so that ultrasonic waves can effectively penetrate into the workpiece to achieve the purpose of detection.
