Argonne Embraces Concept of “in operando” Formation of Carbon-based Tribofilms

23.08.2016

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 [...]
Lubrication and Energy Efficiency

17.04.2023

Energy efficiency is a term used to describe the practice of using less energy to perform a specific task or achieve a particular outcome. It is an essential concept that has become increasingly important in [...]
Engineers create most wear-resistant metal alloy in the world

03.09.2018

If you’re ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid — not drive, skid — [...]
High-speed camera shows incoming particles cause damage by briefly melting surfaces as they strike

24.01.2019

Video of the impact of a 10-micrometer particle (coming in from the left) traveling at more than 1 km/sec shows clearly the splashing away of molten material from the surface at the moment of impact. [...]
Employing machine learning to create wear and corrosion resistant metallic glass

23.04.2018

If you combine two or three metals together, you will get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns. But once in a while, under [...]
