In the past 20 years, thin film lubrication, nano lubrication, friction and lubrication under extreme conditions, biological lubrication, green lubrication and minimal quantity lubrication made important progresses. In recent 10 years, the research on superlubricity, bionic lubrication, intelligent lubrication and monitoring, tribological testing technology and simulation technology was developed rapidly. Micro research became the main means of lubrication research, and the research on lubrication and sealing for wind turbine, high-speed rail, deep space exploration, deep sea exploration, large aircraft, ultra-high speed aircraft, new energy vehicles and so on became the focus of industry, and the research on green lubrication and near zero emission lubrication became the focus of enterprises. As a new subversive technology in the field of lubrication, superlubricity gradually showed unparalleled advantages and vitality in industrial productions and human daily life. Biological lubrication, including friction and lubrication in human organs and bionic research, played an important role in human healthy life. Friction and lubrication under extreme conditions (high temperature, ultra-low temperature, vacuum, high pressure, etc.) were widely used in satellite, rocket, ship, nuclear power station and other national defense facilities. The development of intelligent lubrication and other emerging fields also applied intelligence to the field of lubrication, which provided a new idea for the intelligent operation and manufacturing of equipment. Several important development directions in the field of lubrication, such as superlubricity, thin film lubrication, nano lubrication, extreme friction and lubrication, intelligent lubrication, bio bionics, green friction and lubrication, and tribology test methods were reviewed herein. The latest research progresses of peers at home and abroad were introduced, and looked forward to the future.
