Annotation	The method is demonstrated on various thin film–substrate systems.Start of the AE recording is synchronized with the start of the actual load and penetration of the stylus tip (during the scratch test), which enables very accurate matching of acoustic events with the progress of method of the scratch test. It can be mainly used for investigation of brittle films.It can reveal cohesion rupture either on the surface or inside of the material or adhesion ruptures of the film to the substrate. The method is also useful for investigation of transparent films in cases where the microscopic scanning is failing. Results of testing experiments are presented and compared.
