Research progress of surface modification and solid–liquid lubrication synergistic friction reduction and wear resistance

Friction and wear is a common phenomenon in production and life, and it is also a problem that cannot be eliminated. Friction has a positive side, but it also brings many problems, and the positive side should be used. Tribology is a subject specializing in the study of friction, wear, and lubrication. In recent years, after the joint research of scholars from all over the world, fruitful results have been achieved in the research of tribology in the fields of manufacturing, materials, and medicine. This paper firstly introduces the friction and wear problems in today's world, as well as the economic and environmental problems brought about, and shows the research status and its far-reaching influence in various fields; film technology and lubrication technology were analyzed, the working mechanism of each technology was explained, and the advantages and disadvantages of each technology were shown; the synergy brought about by the combined use of various technologies was mainly discussed, and the synergy of each technology was demonstrated by examples. The advantages of solving the tribological problems at the current stage, the combined use of two or more technologies can make up for each other to a certain extent. Finally, the full text is summarized and the prospect of multi-technology collaboration is prospected.
