Welcome to the GACHOT tribology research unit!

Tribology is the science and technology of interacting surfaces in relative motion

The GACHOT tribology research unit at the TU Wien studies lubricant-surface interactions, functionalised surfaces for tribological applications, near surface damages in tribological contacts (materials tribology) and new approaches to model contact phenomena at different scales.

Our contributions focus on basic research and the transfer of knowledge to industrial applications with an emphasis on machine elements.

Research

Extremely Low Friction Thanks to New Solid State Lubricant

18. February 2025

[Translate to English:] Graphik mit Molekülstrukturen — © Nagaraju Myakala, TU Wien / Wiley

By combining organic and inorganic chemistry, scientists at TU Wien developed the innovative lubricant COK-47 - with remarkable capabilities.

Faster friction - less wear

06. September 2022

[Translate to English:] Drei dreidimensionale Computerdarstellungen der Metallstruktur: Quader bestehend aus kleinen unregelmäßigen Körnchen.

A seemingly paradoxical effect: friction normally causes more damage at higher speeds. But at extremely high speeds, it is the other way around.
