Abstract:Surface weaving technology is a technology to prepare geometric arrays with certain arrangement rules on the surface of the material, through surface texture technology modified materials can effectively improve the tribological properties of mechanical parts, and micro-parts materials, which are now more and more widely used in many engineering fields. In recent years, automotive engines are developing in the direction of high power and high speed, and the application of surface texture technology to automotive engines to improve the tribological properties of crankshaft bearing friction subsets to ensure that the engine can maintain good performance under various operating conditions plays an important role. This paper firstly introduces the main achievements of surface texture technology in the field of tribology in recent years; after that, the different aspects such as surface texture shape, depth, area occupancy, and arrangement are classified and reviewed; the friction and wear reduction and anti-wear properties of the modified surface texture of materials are reflected according to the friction coefficient and wear amount. In order to enhance the performance of the engine, the service life of the automotive engine under severe conditions is improved. Finally, the future development trend of surface texture applied to automotive engine crankshaft is prospected and predicted.
