Abstract

A device for testing the adhesive strength of a coating on a substrate, containing a unit for generating mechanical stress in a predefinable surface area of the coating and an evaluation system, which contains a unit for image acquisition and a unit for evaluating the cracks that occur, wherein the device further contains a transport unit, by which the substrate can be moved at least from the unit for generating mechanical stress to the evaluation system, and a heating unit, by which the substrate can be heated to a predefinable temperature.
