Systems and methods for non-destructive testing of components

Abstract

The present invention relates to a system and method for non-destructive testing of components, and to a hybrid delay line that achieves broadband impedance matching. [Solution] A system (100) for non-destructive testing of a component (104) includes a housing (106), an ultrasonic transducer (108) fixed within the housing (106), and one or more barriers (118) fixed within the housing (106). The one or more barriers (118) are formed of a solid material. A liquid-holding chamber (114) is provided between the ultrasonic transducer (108) and the one or more barriers (118) within the housing (106). The liquid-holding chamber (114) holds a liquid (116).

Claims

Housing and An ultrasonic transducer fixed inside the housing, One or more barriers, fixed within the housing and made of a solid material, A system comprising a liquid-holding chamber for holding liquid, provided between the ultrasonic transducer within the housing and the one or more barriers.

2. The system according to claim 1, wherein a delay line is defined between the one or more barriers and the liquid in the liquid holding chamber.

3. The system according to claim 1, wherein the solid material is hard water and the liquid is liquid-phase water.

4. The system according to claim 1, wherein the housing is configured to slide on the surface of the component.

5. The system according to claim 1, wherein the one or more barriers include attenuation barriers that contact the ultrasonic transducer.

6. The system according to claim 5, wherein the one or more barriers further include an outer wall barrier connected to the damping barrier, the outer wall barrier being connected to the inner surface of the housing.

7. The system according to claim 6, wherein the one or more barriers further include a retaining barrier connected to the outer wall barrier, and the damping barrier, the outer wall barrier, and the retaining barrier form a closed retainer that provides the liquid retaining chamber.

8. The system according to claim 1, wherein the one or more barriers include a retaining barrier that holds the liquid in the liquid holding chamber.

9. The system according to claim 8, wherein the one or more barriers further include attenuation barriers that contact the ultrasonic transducer.

10. The system according to claim 1, wherein the housing includes a retaining recess at its distal end, and the retaining recess is configured to hold another liquid outside the liquid holding chamber.
