Abstract
It is estimated that about 1 / 3 ~ 1 / 2 of the world’s energy consumption is caused by friction and wear. About 80% of the parts of general machinery and equipment are scrapped due to wear. In China, the annual loss caused by friction is more than 4 trillion. Therefore, to explore the origin of friction and realize solid super sliding has become a key point of people’s attention. But the basic scientific principle and mechanism of friction origin are difficult to explore, so how to give a reasonable method to solve this problem is particularly important. This paper focuses on the use of Raman spectroscopy to observe the solid super slip phenomenon and phonon dissipation, through Raman spectroscopy to determine the orientation of molecules on the friction interface, detect the related properties of two-dimensional materials, as well as crystal defects and their apparent morphology to explore the origin of friction, and to reduce the energy loss caused by friction.
