ELECTRO-ULTRASONIC SPECTROSCOPY FOR TESTING QUALITY OF RESISTIVES MATERIALS
Original language description
The ultrasonic signal is widely used in non-destructive spectroscopy. The paper presents the new method of the non-destructive testing of resistives materials. The non-linear elec-tro-ultrasonic spectroscopy is new method which has higher sensitivity andrange of using than common ultrasonic testing method which has many problems. This non-destructive method consists of two signals. The electric ac signal with frequency fE and the ultrasonic signal with frequency fU. The ultrasonic signal changes the resistance ?R of the measured sample by frequency of ultrasonic excitation fU. Defects in the material are causer larger changes resistance ?R then in the material without defects for the same amplitude of ultra-sonic signal.
