“…Combined with acid-alcohol system superlubricity, acid and glycerol system superlubricity, alkali solution superlubricity, etc., three major mechanisms can be summarized to achieve liquid superlubricity, the electric double layer effect [109,110], hydrodynamic effect [111][112][113], and hydration effect [114][115][116], as shown in Figure 13, which are also recognized in the world. Sometimes one mechanism can realize superlubricity, and sometimes the joint action of two to three mechanisms is needed [117][118][119][120]. Under the support of these three mechanisms, the liquid superlubricity pressure capacity can be increased from about 10 MPa in the past to 300 Mpa.…”

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.

“…In summary, we can conclude that the melting-induced effect has been confirmed, indicating that the coefficient of friction (COF) is lower for liquid-like (or quasi-liquid) materials. This phenomenon can be primarily attributed to the transition from solid film lubrication to liquid (or quasi-liquid) lubrication, as proposed in the tribological model [256,257].…”

Transition metal nitride (TMN) films with excellent hardness and lubricating performance are versatile low dimension materials, which are widely used in various fields including industries, transportation, aerospace, and so on. This paper introduces one film design strategy and provides a review of the mechanisms for strengthening and lubricating nitride films. The design strategy refers to two aspects which determine the structures, the performance, the components, and the chemical constitutions of nitride films The strengthening mechanisms of nitride films are then illuminated in detail, including the solid solution effect, the grain size effect, the secondary phase effect, the stress or stress field effect, the template effect, and the valence electron concentration effect. Five lubricating mechanisms are next summarized, including the easy-shear nature, the tribo-chemical reactions, the lubricious fluorides, the textured contact surface, and the synergistic effect. This paper aims to give a comprehensive introduction for understanding the mechanisms of strengthening and lubrication of nitride films for students and researchers, as well as to understand the current research progress in nitride films for exploring research gaps.

“…As one of the most excellent lubricants in solid lubrication [16][17][18][19], DLC still attracts extensive attention in the field of tribology. The research achievements of superlubricity of DLC film are mainly reflected in two aspects, namely, new DLCbased lubricants and lubrication mechanism related to DLC.…”

In the past ten years, the scope of influence of tribology in various fields has been expanded, and the research activities related to superlubricity have also increased greatly. The latest development of superlubricity in recent three years is summarized and the future research direction is prospected. Different aspects of superlubricity have been overviewed. As a highly interdisciplinary field, superlubricity's studies are widely distributed among various disciplines, and there are many aspects of superlubricity that are not covered in this review. Despite the limitations, our group hoped that the overview will bring together recent outstanding researches and be of benefit to the growing number of tribology researchers.
