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

23.08.2016 Rick Shankman 477 Views

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 271 Views

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 579 Views

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 […]

Researchers simulate wear of materials as they rub together

Forty years ago, MIT emeritus professor of mechanical engineering Ernest Rabinowicz calculated that 6 percent of the annual U.S. gross domestic product was lost through mechanical wear. His assertion gained enough traction that it became [...]
Minimal Quantity Lubrication: Drop on Demand Printing Technique

20.04.2020 577 Views

Recent research (https://doi.org/10.1007/s40544-017-0183-5) has shown that about 23% of the world’s total energy consumption comes from the tribological contacts (moving parts subject to friction and wear, such as bearings, gears, etc.). This energy is lost, [...]
Experimental measurement of adhesion and friction in mesoscopic graphite contacts

07.02.2016 80 Views

Two-dimensional materials, such as graphite, expose an intriguing, but poorly understood low-friction behavior – superlubricity. Various aspects of superlubricity have been addressed by researchers, mostly based on theoretical considerations, however, accurate experimental measurements of adhesion [...]
Roughness of the solid particles controls the viscosity of suspension

The internet is full of videos of people having fun running over white slime. It almost looks as if they were walking on water. But when they stand still, they slowly begin to sink. The [...]
Triboelectric charges on HDPE are strain induced
