Percolation in Static Seals
20.12.2021 Dr Francesc Pérez-Ràfols

It might seem weird to talk about percolation through static seals in a Tribological context. After all, they are static: there is no rubbing, no tribos. However, there is much to learn about percolation through […]

Atomistic Tribology
Atomic scale deformation responsible for surface roughness
04.05.2020 TriboNet

Most of the natural or engineered surfaces are not perfect, meaning they are rough. The surface roughness was found across many scales: from atomic to tectonic. The earth looks smooth from space, but someone standing […]

Tribology on the Small Scale: A Modern Textbook on Friction, Lubrication, and Wear
04.12.2019 Aydar Akchurin

In recent decades, tribology field has seen a great interest in friction and wear processes occurring at the micro- and nanoscale. This interest has led to the development of a new branch of tribology focusing on the small […]
