Effect of electrode potential on the tribocorrosion of tungsten

Didier Bouvet, Michel Declercq, Stefano Mischler, Jelena Stojadinovic

The tribocorrosion behavior of tungsten sliding against an alumina ball was evaluated in sulfuric acid under applied electrode potential. Surface chemistry of worn and unworn surfaces was evaluated using XPS and AES. Quasi-potentiostatic polarization curve ...

Electrochemically controlled wear transitions in the tribocorrosion of ruthenium

Didier Bouvet, Michel Declercq, Stefano Mischler, Jelena Stojadinovic

This work presents an investigation of the tribocorrosion of ruthenium in sulphuric acid solutions. The study was focused on the effect of the electrode potential on wear of ruthenium during sliding against an inert alumina ball in a reciprocating sliding ...

Influence of emulsion composition on lubrication capacity and texture perception

Stefano Mischler

P>The role of fat content and type of surfactant for oral friction processes and texture perception of oil-in-water emulsions was assessed. Emulsions at 22% and 33% fat content containing either sodium caseinate or a sucrose ester as emulsifier were compar ...

Methods for functionalization of microsized polystyrene beads with titania nanoparticles for cathodic electrophoretic deposition

Stefano Mischler, Johann Michler

Functionalization of colloidal particles based on the use of polyelectrolytes and heterocoagulation was combined with electrophoretic deposition (EPD), with the aim of depositing titania-polystyrene (TiO2-PS) composite particles on Ti6A14V substrates. The ...

Triboelectrochemical techniques and interpretation methods in tribocorrosion: A comparative evaluation

Stefano Mischler

Tribocorrosion is a material deterioration or transformation resulting from simultaneous action of wear and corrosion. Tribocorrosion is found in many engineering applications but the involved mechanisms are still little understood. The investigation of tr ...

Effect of filler behavior on nanocomposite SU8 photoresist for moving micro- parts

Stefano Mischler, Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

The use of low-stress SU8 nanocomposites as a functional material for micro- parts and coating applications is described in this paper. It was found that the nanoparticles lower the internal stress and decrease the wear rate and frictional coefficient of t ...

SU-8 nanocomposite coatings with improved tribological performance for MEMS

Heinrich Hofmann, Stefano Mischler, Philippe Renaud, Arnaud Bertsch, Sébastien Jiguet

The increasing interests in micro-electro-mechanical systems (MEMS) has raised the requirement for photoresist materials with improved friction and wear properties for mechanically loaded 3D shaped microstructures. In this work, SU8 photoresist layers rein ...
