Tribologische Untersuchungen mikrostrukturierter B4C-Schichten

Abstract

Im Rahmen der vorgestellten Ergebnisse wird das Potential von dünnen Borkarbid-Schichten (B4C) hinsichtlich tribologischer Anwendungen untersucht. Dafür werden stöchiometrische B4C-Schichten mit verschiedenen mechanischen Eigenschaften mittels Laserpulsabscheidung auf Stahl mit Schichtdicken von 1 μm abgeschieden. Diese teils superharten Schichten werden anschließend durch Lasermikrostrukturierung mit Mikrostrukturen versehen, deren Einflüsse auf die tribologischen Eigenschaften anschließend mittels ball-on-disc-Verfahren im Tribometerversuch bestimmt werden. Die Charakterisierung sowohl der unstrukturierten als auch der strukturierten Bereiche erfolgt neben Rasterelektronenmikroskopie und Atomkraftmikroskopie insbesondere durch Ultrananoindentation zur Bestimmung der mechanischen Eigenschaften.

In the context of the presented results, thin boron carbide coatings (B4C) are investigated concerning their potential for tribological applications. Stoichiometric B4C thin films with varying mechanical properties are deposited onto steal using pulsed laser deposition (PLD). Film thicknesses are in the range of > 1 μm. Subsequently, these partially super hard coatings are modified with certain structures using laser micro structuring. The influence of these microstructures on the tribological behavior of the films is investigated using ball-on-disc measurements. Both the modified and the nonmodified regions of the thin films are characterized by scanning electron microscopy, atomic force microscopy and instrumented ultrananoindentation in order to estimate the mechanical properties
