“…Later, they developed a thermal-assisted mechanical peeling and transfer method, which wrapped different types of two-dimensional materials on the AFM tip so that the tip could directly detect the interlayer coupling, and they achieved a friction coefficient of 10 −4 ~10 −5 , all of which had nothing to do with the sliding direction [73]. There is still a lot of work being carried out in this field, which will deepen and expand the research on superlubricity [74,75]. It is worth noting that the superlubricity theory is based on the incommensurability of two crystal planes, so the superlubricity is dependent on the slip direction, that is, it can only be realized in a specific slip direction.…”

Friction and the wear caused by friction will not only lead to energy dissipation, but will also cause damage to the function of mechanical parts, affecting the precision and lifespan of mechanical devices. Superlubricity as an ideal state of zero friction has become a hot research topic in recent years. There have been many reviews on the concept, origin, and research progress of superlubricity, but, among them, there are more presentations on the research status of solid superlubricity and liquid superlubricity; however, the theoretical summarization of solid–liquid combined superlubricity and high-temperature superlubricity is still imperfect and lacks a systematic and comprehensive review. The mechanism of superlubricity is not explicitly presented in many reviews, which are clearly summarized in this paper. This paper introduces superlubricity from friction, and then introduces the origin of superlubricity, and presents the research progress on superlubricityby separating it into in four categories: liquid superlubricity, solid superlubricity, solid–liquid combined superlubricity, and high-temperature superlubricity. By analyzing the superlubricity system, the mechanism of realizing various types of superlubricity, such as incommensurability, hydration, and oxidation, is summarized. Based on the research progress of superlubricity, the development prospects, opportunities, and challenges of superlubricity in the future are discussed.
