Infrared thermography technology is an important nondestructive testing technology(NDT).The advantages of this technology is significant compared with traditional nondestructive testing technologies.Starting from the contact fatigue damage form of thermal sprayed coating,the application status of traditional NDT in coating fatigue life prediction research is reviewed,and infrared thermography technology application examples on coating serving,thickness and defects detection,etc are introduced.In the meantime,the application status of fusion infrared thermography technology in material fatigue limit determination,structural health diagnosis and crack monitoring and other fields is also summarized.The problems in the method is pointed out too.The application and research of information fusion on contact fatigue life prediction of thermal sprayed coating is prospected.
