Surface texture technology is a technology that prepares a geometric network with a certain arrangement on the surface of a material. The materials modified by surface texture technology can effectively improve the tribological properties of mechanical parts and micro-part materials. It is now more and more widespread It is used in many fields of engineering. In recent years, automotive engines have developed in the direction of high power and high speed.Surface texture technology has been applied to automotive engines to improve the tribological performance of friction pairs of crankshaft bearings and ensure that the engine can maintain good performance under various operating conditions. play an important role. This article first presents the main achievements of surface texture technology in the field of tribology in recent years; then it classifies and summarizes the shape of the surface texture, the depth, the occupancy rate of the area, the method of arrangement and other aspects; According to the coefficient of friction, the amount of wear reflects the surface texture of the material Friction and wear resistance after structural modification. In order to improve the performance of the engine, the life of the automotive engine under harsh conditions is increased. Finally, the future development trend of the surface texture applied to the automotive engine crankshaft is explored and predicted.
