Abstract：The rapid industrial development in China is requiring more energy consumption based on non-renewable energy resources. The energy consumption caused by unnecessary friction accounts for about 4.5% of the GDP in China. Many researchers in tribology are investigating superlubricity applications to reduce friction in machinery. Superlubricity improves the lubrication efficiency which reduces the energy consumption and considerably increases the energy utilization rate. This study reviews superlubricity characteristics and mechanisms for lubrication applications. The characteristics of recently developed liquids are reviewed with descriptions of the liquid superlubricity mechanism. Finally, the advantages and disadvantages of the current research on superlubricity are summarized.
