Method and apparatus for detecting corrosion under non-ferromagnetic coatings |
| abstract |
A method using nuclear magnetic resonance techniques to detect corrosion within metallic structures such as aluminum under non-ferromagnetic coatings without first having to remove the coatings. The metallic structure is placed within an external static magnetic field. A series of radio frequency preparation pulses (34) and inspection pulses (36) is applied to the metallic structure, for exciting and disturbing the equilibrium orientation of the hydrogen nuclei within the metallic structure with the preparation pulses (34), and for generating a series of nuclear magnetic resonance signals (38) with the inspection pulses (36). The response signals (38) are detected and the amplitude of the response signals (38) is compared with the spin-spin relaxation time of corrosion for detecting the presence of corrosion in the structure. |
