Argonne Embraces Concept of "in operando" Formation of Carbon-based Tribofilms

23.08.2016 Rick Shankman

Earlier this month, tribologists and physicists at the U.S. Department of Energy (DOE) Argonne National Laboratory published news of their (self-described) “self-healing diamond-like carbon coating [that] could revolutionize lubrication” in the journal Nature. The researchers […]

Switchable Friction on Graphene

15.08.2016 Dr. Aydar Akchurin

Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]

Adhesive Wear Particles Generation: by Fracture or Atom-by-Atom?

01.08.2016 Dr. Aydar Akchurin

The most famous equation to predict wear known probably to everyone working in the field of tribology is Archard’s model (1953). The model assumes that wear occurs through the fracture of plastically deformed material and […]

Contact Area Calculation Tutorial: Boundary Element Based Model vs. Asperity Based Model

14.03.2018

In contact mechanics and tribology it is frequently needed to calculate the contact area between rough surfaces to estimate possible slip, friction, electric conductivity, etc. In this tutorial, it will be shown how to perform [...]
Bi-layered materials: graphene - no heat, no friction; h-BN - as strong as diamond.

20.09.2017

A group of researchers from Queen’s University Belfast have discovered a stretchy miracle material that could be used to create highly resistant smart devices and scratch-proof paint for cars. Led by Dr Elton Santos from [...]
Snake skin inspired texture to control friction

22.06.2018

If you want to know how to make a sneaker with better traction in the rain, just ask a snake. That’s the theory driving the research of Hisham Abdel-Aal, PhD, an associate teaching professor from [...]
How to get sprayed metal coatings to stick

04.12.2017

Micrographs of a metal surface after impact by metal particles. Craters are formed due to melting of the surface from the impact. Image courtesy of the researchers. “When spraying metal coatings, melting hurts rather than [...]

Sediments Act As Lubricants for Plate Tectonics

09.09.2019

Plate tectonics explains the features and movement of the Earth’s surface both in the present and in the past. It is the theory that the outer shell of Earth is divided into many plates (including [...]
