Abstract

The problem of the main factors infl uence on the electro-magnetic energy to ultrasound conversion in test-ing of electrically conductive or ferromagnetic materials is considered.

The necessity to provide the polarizing magnetic fi eld induction maximum value and the maximum current in the electromagnetic-acoustic transducer high-frequency coil is shown.

A converter for co-radiation and reception of pulses of ultrasonic vibrations has been developed and tested, providing useful information signal amplitude of up to 50 dB.
