What is fretting? Fretting or fretting wear is a specific wear type which is characterized by low amplitude oscillating sliding between bodies, which are nominally at rest [1] (for example due to vibration, cyclic stresses, […]

Tribology in Animal World: Dietary Habits of Lepidosauria Studied via Dental Microwear

07.10.2019

Scientists from the Johannes Gutenberg University Mainz are studying the tooth enamel surface of lepidosauria. Lepidosauria are reptiles with overlapping scales and include approximately 7150 species of lizards, snakes, tuatara and amphisbaenians (worm lizards). The [...]
What is the difference between reciprocated and non-reciprocated sliding?

23.10.2019

Sliding mode is an often overlooked aspect of tribological testing; in some applications surfaces are reciprocated with respect to each other, while in other applications the slider only contacts fresh counter surface. For example, in [...]
Electric vehicles: less challenges for tribologists?

16.11.2020

With the last years’ rise of electric vehicles (EV), you may have thought that the future lubrication challenges for cars may not be challenging anymore. At least not as challenging as the ones that the [...]
Decrease Friction with Hydrogen Ions

13.06.2016

Currently, a large portion of consumed energy is used to overcome friction. Design of low friction components is a primary goal in building a sustainable society. Superlubricity, the state of ultralow friction (<0.01), has already [...]
White etching cracks

Today, bearing failure due to rolling contact fatigue is generally a rare occurrence, and the ﬁnal achieved service life of rolling bearings is usually well in excess of the calculated rating life. There are instances, [...]
