【摘要】：钢铁材料广泛应用于诸多工程领域,但其耐磨性差,源于材料表面的摩擦会引起磨损损伤、阻力大、噪声污染等问题,从而导致材料损伤或失效,影响部件局部或整体的正常使用。在材料表面形成表面织构可有效实现减摩/抗磨、减阻、降噪的效果,从而达到改善钢铁材料摩擦学行为的目的。综述了表面织构在改善钢铁材料摩擦学行为方面的研究现状,对钢铁材料表面减摩/抗磨、减阻和降噪表面织构的设计与研究进行了分析与比较,简要阐述了相关机理。干摩擦和润滑条件下,表面织构通过发挥捕捉磨屑、储存润滑剂、流体动压润滑的作用来实现减摩/抗磨;与流体和空气摩擦时,表面织构通过产生二次涡达到减小表面与流体/空气接触面积等作用实现减阻和降噪。最后,展望了能够改善钢铁材料摩擦学行为的表面织构的相关研究思路和方法。
[Abstract]:Iron and steel materials are widely used in many engineering fields, but their wear resistance is poor, because of the friction on the surface of the materials will cause wear damage, high resistance, noise pollution and other problems, thus leading to material damage or failure. Affects the normal use of parts locally or as a whole. The effect of friction / wear reduction, drag reduction and noise reduction can be effectively realized by forming surface texture on the material surface, thus improving the tribological behavior of iron and steel materials. The research status of surface texture in improving the tribological behavior of iron and steel materials is reviewed. The design and study of surface texture of iron and steel materials for friction / wear reduction, drag reduction and noise reduction are analyzed and compared, and the related mechanisms are briefly described. In dry friction and lubrication, surface texture reduces friction / antiwear by capturing debris, storing lubricant, and hydrodynamic lubrication; when friction with fluid and air, Surface texture reduces drag and noise by generating secondary vortices to reduce the contact area between surface and fluid / air. Finally, the related research ideas and methods of surface texture which can improve tribological behavior of iron and steel materials are prospected.
