Revealing cation and metal gradients in and underneath passive films of the stainless steel 1.4652 in acidic and alkaline electrolytes with angular resolved dual energy X-ray photo-electron spectroscopy

Patrik Schmutz, Stefano Mischler, Anna Neus Igual Muñoz, Roland Hauert

Passive films on the superaustenitic stainless steel 1.4652 were studied using angular resolved hard X-ray photo-electron spectroscopy (HAXPES), which provides an increased information depth compared to conventional X-ray photo-electron spectroscopy (XPS). ...

A methodology for characterizing the electrochemical stability of DLC coated interlayers and interfaces

Patrik Schmutz, Stefano Mischler, Emilija Ilic, Roland Hauert

DLC coatings are often deposited on Si and Cr based adhesion-promoting interlayers to mitigate stress at the DLC/substrate interface. Interlayers reduce the likelihood of mechanical coating delamination. However, their chemical stability at miniature DLC c ...

Silicon Corrosion in Neutral Media: The Influence of Confined Geometries and Crevice Corrosion in Simulated Physiological Solutions

Patrik Schmutz, Stefano Mischler, Emilija Ilic, Roland Hauert

Silicon (Si) based implantable components are widely used to restore functionalities in the human body. However, there have been reported instances of Si corroding after only a few years of implantation. A key parameter often overlooked when assessing Si s ...
