Wear is a gradual removal of the material of the bodies during their interaction. The process appears in many mechanical systems, ranging from large scales, as in wind mills, to nanoscales, as in the AFM […]
When the bodies slide against each other, the classic Amonton’s law states that the friction force is directly proportional to the applied normal load. This law holds true for various if not most of the […]
Superlubricity is a phenomenon of vanishing friction, which can be used to increase the efficiency of many mechanical devices and reduce the energy costs. The phenomenon is not well understood and mostly is observed in […]
Tiny, sub-micron sized particles are frequently used as additives in the lubricants to improve their frictional and wear behavior. These particles, due to their size, can enter the contact and protect the surfaces from the […]
Friction has been a challenge for the mankind throughout the whole history since it resists the motion. It resists the transportation of goods. And transportation shares 20% of the global energy consumption and approximately 18% […]
Gravitational waves were proved to exist, thus validating one more prediction by Albert Einstein and his general theory of relativity! Is there any relation between the relativity and Tribology? It looks like there is! “Micromechanisms […]
As it was already pointed in the recent post, the friction on ice is an important topic and its typical low value is attributed to the formation of the water film. Despite our everyday life […]
Forbidden City is a historical symbol of China, located in the center of Beijing and was constructed between 1406 and 1420 . It served as an imperial palace for almost 500 years and consists of […]
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 […]
Darvin’s theory of evolution is widely held concept which states that all the life has evolved from a common ancestor: fruits, animals, trees, flowers. During the gradual process of evolution, beneficial random genetic mutations in […]
