NEW POSIBILITIES IN NON DESTRUCTIVE TESTING BY ELECTRO-ULTRASONIC SPECTROSCOPY
Original language description
This paper describes the electro-ultrasonic spectroscopy as method of non-destructive testing. Electro-ultrasonic spectroscopy is based on interaction of ultrasonic signal and electric signal in conductive materials. Ultrasonic signal changes the contactarea between conducting grains in the sample, thus resistance of the sample is modulated by frequency of ultrasonic excitation. Defects and cracks in the sample structure are the sources of new intermodulation signal. The frequency of this signal is given by superposition or subtraction of exciting frequencies. This method is very sensitive because helps to evaluate the intermodulation signal on the frequency different from exciting frequencies of electrical and ultrasonic signal.
