Abstract (en)
[origin: WO2017191008A1] The invention relates to a method for forming and detecting security elements on the surface of a component and/or in a component, wherein, on the surface of the component and/or in the component, which is formed of a magnetic or a non-magnetic material, at least one layer or at least one area preferably formed with a magnetic material or a material different from the component material is formed in a locally and geometrically defined manner. At least one removal track, at least one heat-affected area, and/or at least one remelted treatment track is formed on the surface of a component along a specified contour corresponding to the security feature in question by means of a locally and geometrically defined material removal or energy input. When the component is produced by means of an additive production method, a magnetic material different from the material of the component is inserted into the component in at least one specified position in a locally and geometrically defined manner. In order to detect the security element by means of a magnetization unit, at least one magnetic field penetrating the component is generated or one magnetic flux is produced within the magnetization unit, which magnetic flux penetrates the component. In order to check a security element formed in such a way, the magnetic stray fields occurring at the security element as a result of the at least one magnetic field are detected by means of a detection unit and the measurement signals captured by means of the detection unit are transmitted to an evaluating unit having an image-processing or pattern recognition system. The evaluating unit having the image-processing or pattern recognition system is used to check, by means of the detected magnetic stray fields, whether the detected security element matches a specification or not.
