Surprisingly, when two lubricated solids are heavily loaded against one another and when a motion is applied to the solids surfaces, these two solids may not be touching one another (see Figure 1, left)! This […]

Superlubricity state through atom-by-atom surface tuning

18.01.2016

Friction is everywhere around us, working against motion of cars, airplanes, their engines, wind mills and other devices causing wear and decreasing their energy and overall performance efficiency. However, there exists a certain state, called [...]
A very simple estimate of adhesion with rough surfaces based on a bearing area model

19.02.2018

Here we present an abstract to the paper addressing a simplified model for adhesion between hard rough solids. Abstract In the present note, we suggest a single-line equation estimate for adhesion between elastic (hard) rough [...]
Sandia Researchers Identified Nanoscale Mechanisms of Steel Corrosion

05.08.2019

Corrosion is a naturally occurring process, which converts refined metals into a more chemically stable form. This could be an oxide, hydroxide, or sulfide. Corrosion is the gradual destruction of metals by chemical or electrochemical [...]
Tribology at Work on the Strings

12.07.2017

There’s something about the moan and wail of a good gut-bucket slide guitar riff that can grab you by the innards and not let go. Any tribologist worth his salt is likely to have another [...]
Mixed Lubrication: Wear Particles Size and Friction Evolution

10.04.2017

Wear in tribological contacts results in generation of wear particles of various sizes and shapes and these particles impact the performance of the mechanical devices. These particles may create additional mechanical damage or act as [...]
