Abstract

In the last fifteen years computer-tomography has proven to be a valuable aid in the fields of medicine, materials technology and forensics. Nowadays it is hard to image non-destructive testing being carried out without its use. This article serves to demonstrate the power of the technique within the field of failure analysis with reference to two chosen case studies. The first case concerns the failure of magnetic valves, the second case focusses on the failure of corrosion resistant screws.

Kurzfassung

Die Computertomographie hat sich in den letzten fünf Jahrzehnten zu einem wertvollen Hilfsmittel im Bereich der Medizin, Werkstofftechnik und Forensik entwickelt. Heutzutage ist dieses Verfahren aus dem Bereich der zerstörungsfreien Werkstoffprüfung nicht mehr wegzudenken. Anhand von zwei ausgewählten Fallbeispielen soll die Leistungsfähigkeit dieser Methode im Bereich der Schadensanalytik demonstriert werden. Der erste Teil beschäftigt sich mit dem Ausfall von Magnetventilen. Beim zweiten Fall steht das Versagen korrosionsbeständiger Schrauben im Mittelpunkt.
