Abstract

Microscale machining processes modifying component surfaces are applied in various fields: from drive technology through plant engineering to medical technology. The impact of the fine structures formed in the material on its behavior and mechanical properties need to be investigated in more detail. Besides the examination of the cyclic and quasi-static behavior of micromachined samples, analysing the near-surface microstructure and the hardness is of great importance. The nanoindentation allows for the determination of local mechanical properties in small analysis volumes. Its applicability to determine the hardness in micromachined near-surface areas including the metallographic preparation for commercially pure titanium is presented in this work.

Kurzfassung

Bearbeitungsverfahren auf der Mikroskala zur Modifizierung von Bauteiloberflächen finden in verschiedenen Bereichen von der Antriebstechnik über die Anlagentechnik bis hin zur Medizintechnik Anwendung. Den Einfluss der eingebrachten feinen Strukturen auf das Werkstoffstoffverhalten und die mechanischen Eigenschaften gilt es tiefergehend zu erforschen. Neben der Untersuchung des zyklischen und quasistatischen Verhaltens von mikrobearbeiteten Proben ist die Analyse des oberflächennahen Gefüges und der Härte von hoher Bedeutung. Die Nanoindentation lässt die Bestimmung lokaler mechanischer Eigenschaften in kleinen Analysevolumen zu. Die Anwendbarkeit dieses Verfahrens zur Bestimmung der Härte in oberflächennahen mikrobearbeiteten Bereichen inklusive metallographischer Präparation für den Reinwerkstoff cp-Titan wird in dieser Arbeit vorgestellt.
