Abstract
A system for evaluating a bond includes a first electrode and a second electrode that are spaced apart from one another. The system also includes a sacrificial material layer positioned proximate to a surface of a bonded structure that includes the bond. The system also includes a power source configured to cause the first and second electrodes to generate an electrical arc that at least partially ablates the sacrificial material layer as part of a non-destructive inspection of the bond.
Claims20
A system for evaluating a bond, comprising:
- a first electrode;
- a second electrode spaced apart from the first electrode;
- a sacrificial material layer positioned proximate to a surface of a bonded structure that includes the bond;
- and
- a power source configured to cause the first and second electrodes to generate an electrical arc that at least partially ablates the sacrificial material layer as part of a non-destructive inspection of the bond.

A system for evaluating a bond, comprising:
- a first electrode;
- a second electrode;
- a dielectric material layer positioned at least partially between the first electrode and the second electrode, such that the second electrode is not in contact with the first electrode;
- a sacrificial material layer positioned in contact with a surface of a bonded structure that includes the bond, wherein the sacrificial material layer is positioned on a same side of the dielectric material layer as the second electrode and a different side of the dielectric material layer than the first electrode;
- and
- a power source configured to transmit an alternating current pulse to the first and second electrodes, which causes the first and second electrodes to generate an electrical arc that at least partially ablates a sacrificial material layer to generate a plasma, wherein the generation of the plasma generates a first wave that is directed into the bonded structure, and wherein the first wave reflects off of the bond in the bonded structure as a second wave.

A method for evaluating a bond, comprising:
- placing a sacrificial material layer on a surface of a bonded structure;
- and
- generating an electrical arc to least partially ablate the sacrificial material layer, which generates a first wave that is directed into the bonded structure, wherein the first wave reflects off of the bond in the bonded structure as a second wave.
