FIELD: nondestructive tests. SUBSTANCE: due to choice in proposed limits of shares of epoxy resin, ferribarium powder, polyester and polyethilenepolyamine in damping mass, sufficient to test sticky mediums amplitudes of converter emitted and received ultrasonic signals are provided. Duration of received signals and inclination o their fronts are sufficient to determine time of their arrival with high accuracy. EFFECT: improved operational characteristics of converters with the damping mass during ultrasonic tests of sticky medium.
