METHOD FOR FABRICATING AND TESTING THERMAL-SPRAY COATED SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a method (100) for fabricating and testing an article having a thermal-spray coating. SOLUTION: The method includes a step (102) of providing a substrate article having a surface; a step (104) of 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 bond section; and a step (106) of nondestructively testing the coated article. Nondestructively testing includes a step (108) of generating an eddy current in the coated article; a step (110) of measuring the eddy current in the coated article; and a step (112) of evaluating a near-bond section region of the coated article located adjacent to the bond section using the measured eddy current.
