When the conditions in the tribosystem are such that the lubricant is not capable of carrying any significant part of the applied load, most of the load is carried by the direct contact of the […]
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 […]
Superlubricity is a state of low friction, broadly defined as the state with the coefficient of friction lower than 0.01. This level is not achievable with classical lubrication mechanisms and currently other methods are being […]
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, […]
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% […]
