FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises heating the object to be tested up to a temperature at which the strength of the object drops by at least a factor of 1.5 and the coating in the zone of the unsatisfactory adhesion of coating with the base is deformed. The deformation of the coating indicates the presence of defects. ^ EFFECT: improved method.
