Charakterisierung von biodegradierbaren EPD-Beschichtungen auf Magnesium
Mg als auch Mg-Legierungen besitzen Eigenschaften die sie zu interessanten Kandidaten für temporäre biomedizinische Implantaten macht. Eine der größte Herausforderungen für Mg-Legierungen im biomedizinischen Bereich ist die starke Wasserstoffentwicklung und der Anstieg des pH-Wertes während eines Korrosionsvorgangs. Um die Zuverlässigkeit dieser Implantatmaterialien zu verbessern, ist ein tieferes Verständnis der Korrosionsprozesse notwendig.
Ziel der aktuellen Forschung ist es deshalb, auch biologische Einflüsse auf das Korrosionsverhalten zu untersuchen. Beschichtungssysteme auf der Legierung, als auch deren Grenzflächen werden hierbei untersucht. Träger des Projektes welches in Zusammenarbeit mit Prof. A.R. Boccaccini (Lehrstuhl für Biomaterialien), sowie Prof. F. Witte (Charité Berlin) erforscht wird ist die DFG.

Einfluss von nanostrukturierten Oberflächen auf das Korrosionsverhalten und die Bioaktivität einer TiAl6V4-Legierung unter angepassten in-vitro Versuchsbedingungen
Dieses Projekt untersucht den Einfluss verschiedener nanostrukturierter Beschichtungen auf das Korrosionsverhalten und die Abscheidung von Calciumphosphat unter Langzeit-Auslagerungsversuchen. Organische, anorganische und polymer Beschichtungen auf TiAl6V4 werden hierzu in einem Zellkulturmedium unter physiologischen und simulierten Entzündungsreaktionen ausgelagert. Die Oberflächencharakterisierung erfolgt mittels REM, XPS, EIS und Tof-SIMS. Die Cytotoxizität, Zellproliferation und Mineralisierung der einzelnen Beschichtungen wird anhand von Stammzellendifferenzierung untersucht.

Hochtemperaturoxidation einkristalliner Superlegierungen – Frühstadien und Elementarmechanismen.
Klassische Superlegierungen zeichnen sich als Hochtemperaturmaterialien durch hohen Widerstand gegenüber andauernder statischer und dynamischer Belastung, sowie eine ausreichende Beständigkeit in heißen und aggressiven Atmosphären aus.
Ein Schwerpunkt des Sonderforschungsbereich SFB/Transregio103 sind Elementarmechnismen die während des Einsatzes der Werkstoffe bei hohen Temperaturen stattfinden. Als Teilprojekt wird am Lehrstuhl Korrosion und Oberflächentechnik die Oxidschichtbildung auf Cobalt- und Nickelbasis Superlegierungen untersucht. Im Fokus der Forschung steht der Einfluss von Basismaterial und dessen Mikrostruktur auf die Initiierung der Oxidschichtbildung sowie der Entstehung schützender Oxidschichten. Mit Hilfe eines weiteren komplexen experimentellen Ansatzes können außerdem Erkenntnisse zu Diffusionswege von Sauerstoff durch die bereits gebildete Oxidschicht erzielt werden.

Oberflächenfunktionalisierung und Beschichtung von Magnesium mit Proteinen – Adsorptionsverhalten und Einfluss der Schichten auf die Korrosion und die Biokompatibilität von Magnesium
In diesem Projekt geht es um die Beschichtung des bio-degradierbaren Implantatmaterials Magnesium mit Proteinen. Während physiologische Bedingungen wie der gepufferte pH Wert von ca. 7, die hohe Chloridionenkonzentration und die dynamische Umgebung die Magnesiumkorrosion beschleunigen, werden organischen Bestandteilen wie Proteinen und Zellen passivierende Eigenschaften zugesagt. Idee ist es, die Oberfläche von Mg mit verschiedenen Molekülen, die die Proteinadsorption fördern, zu funktionalisieren und Proteine gezielt als Korrosionsschutz einzusetzen.

Functionalization of stainless steels with hydrophobic layers, influence on wetting and corrosion resistance
In this project it is been studied the corrosion inhibition of tailored hydrophobic and superhydrophobic steel surfaces mainly focusing on stainless steel. It is aimed to find cheap and scalable method to reproduce this kind of surfaces. For this reason organic acids and silanes are deposited by dip-coating and spin-coating over flat and rough surfaces in order to decrease the surface energy and increase the hydrophobicity. It is been studied optimization of the corrosion protection given by these hydrophobic layers analyzing the process time, homogeneity of the layer, nature of the low energy molecule and its concentration.
