Abstract
Thermal barrier coatings are increasingly used in industry for protecting machine components, such as turbine blades, liners and vanes, from aggressive environments and high temperatures. The quality of bonding between a coating and substrate is crucial in ensuring a required lifetime of components. IR pulsed thermography proved to be a useful tool in detecting bonding defects and evaluating coating thickness. The paper is focused on the statistical defect detection and discrimination between delaminations and coating thickness variations.
