🔺 Superlubricity refers to a state where surfaces experience very low friction. Now, researchers at the University of Leicester have made pioneering discoveries in this field. 🔹 In the state of superlubricity, surfaces can experience friction much lower, ranging from 1000 to 10000 times less than normal friction. Additionally, in this state, contrary to the Amontons-Coulomb friction law, the frictional force does not change with an increase in the body's weight. 🔸 Now, a group of scientists led by Professor Nikolai Brilliantov has discovered that simultaneous oscillations of bodies' surfaces, caused by random vibrations of surface atoms, increase friction. These vibrations exist at any non-zero temperature and increase with temperature. This indicates that by reducing the temperature of surfaces, friction can be further reduced. With their new discoveries, researchers were able to formulate the governing laws of the superlubricity phenomenon. Professor Brilliantov says: Such a significant difference in common friction is interesting and requires explanation. There are other remarkable features of superlubricity, such as the unusual dependence of friction force on sliding speed, temperature, and contact surface area. All these dependencies are contrary to those predicted by traditional Amontons-Coulomb laws. 🔹 The importance of these new discoveries in this field lies in understanding the mysterious behavior of superlubricity. By reducing friction, it is possible to reduce losses in mechanical systems and transform energy efficiency in the world. The research results of these scientists have been published in Physical Review Letters, and you can read it here
