TBC Characterization Using Capacitive and Inductive Sensors with Multivariate Inversion Methods

This paper describes flexible inductive sensors, such as the Meandering Winding Magnetometer (MWM) and MWM-Arrays for characterization of conductive nonmagnetic, conductive magnetic and nonconductive magnetic materials; and capacitive sensors, such as the flexible Interdigitated Electrode Dielectrometer (IDED) (MWM and IDED are registered trademarks of JENTEK Sensors, Inc.) for characterization of dielectric materials. These sensors and multivariate inversion algorithms can provide effective nondestructive characterization of thermal spray coatings on complex shape components.
