Nondestructive Inspection of Local Thinning by Infrared Thermography with Stainless Steel Film Heater

抄録

A new heating technique with a stainless steel film and a nondestructive inspection system with the response surface method resolve some of the issues of active thermography. A black painted stainless steel film works as a blackbody surface. As a result, an infrared thermographic camera can easily measure the temperature of a metal surface accurately. The inspection system can identify the shape of the local thinning robustly by selecting the attribute for the shape parameters.
