Abstract
A method for fabricating and testing an article having a thermal-spray coating thereon. The method includes providing a substrate article having a surface, thermally spraying a coating material onto the surface of the substrate article, wherein a surface of contact between the coating material and the substrate article is a bondline, and nondestructively testing the coated article. Nondestructively testing includes generating an eddy current in the coated article, measuring the eddy current in the coated article, and evaluating a near-bondline region of the coated article located adjacent to the bondline using the measured eddy current.
Claims10
A system for use in testing an article having a thermal-spray coating thereon, said system comprising:
- a turntable having a thermally-coated substrate article positioned thereon;
- an eddy current probe operatively coupled to said substrate article, said eddy current probe configured to generate an eddy current within said coated substrate article and to measure the eddy current within said coated substrate article;
- and
- a processor configured to determine a near-bondline region of said coated article located adjacent to a bondline using the measured eddy current.
