METHOD FOR PREPARING AND ULTRASONICALLY TESTING A THERMAL-SPRAY COATED ARTICLE

An article having a thermal-spray coating thereon is prepared by thermally spraying a coating material onto a surface of a substrate article. The coated article is nondestructively tested by directing a transmitted ultrasonic signal into the coated article, receiving a received ultrasonic signal fro...

Beschreibung
Zusammenfassung:	An article having a thermal-spray coating thereon is prepared by thermally spraying a coating material onto a surface of a substrate article. The coated article is nondestructively tested by directing a transmitted ultrasonic signal into the coated article, receiving a received ultrasonic signal from the coated article, and evaluating a near-bondline region of the coated article located adjacent to the surface of the article using the received ultrasonic signal.
