Earlier we reported about superlubricity achieved with a mixture of water and 30 [wt%] glycerol by researchers from Tsinghua University, Beijing. The same investigators just published a paper using this as a base lubricant and […]
It is estimated that the energy lost due to friction in industrialized countries equals to approximately 5% of their gross national products and it is clear, that reducing the friction is highly desirable. The classical […]
In a wide range of tribological components, the lubricant is not capable of separating the surfaces and areas of metal-to-metal contact occurs. However, the metal-to-metal contact area can be minimized by the action of additives, […]
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 […]
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 […]
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 […]
Friction rises when bodies come to contact and start relative sliding. This phenomenon occurs in many mechanical systems and it is estimated that over 30% of the fuel in cars is consumed to overcome friction. […]
