摘　　要：表面织构是陶瓷材料有效的减摩抗磨手段,能够降低陶瓷在滑动时的摩擦因数以及减少因磨损带来的损耗。本文从陶瓷表面织构的制备、类型、几何参数以及摩擦学机理出发,对其进行综合评述。首先,介绍陶瓷材料表面织构主要的制备方法(激光加工、反应离子刻蚀)。其次,讨论表面织构的类型(凸体、凹坑、凹槽、仿生织构等)以及几何参数(宽度、深度、面积占比等)对陶瓷摩擦学性能的影响。随后,分析表面织构在干滑动以及润滑条件下的摩擦学机理。在干滑动条件下,表面织构能困住磨屑以及减小陶瓷与对磨体的接触面积;在润滑条件下,表面织构能改善陶瓷在滑动时的流体动压和润湿性,这均能提升陶瓷的摩擦学性能。最后,总结与展望陶瓷表面织构目前面临的难题以及未来的研究方向。Surface texture is an effective method of friction reduction and anti-wear of ceramic materials,which can reduce the friction factor during sliding and the loss caused by the wear of ceramics.In this work,the preparation,type,geometric parameters,and tribological mechanism of surface texture of ceramics are reviewed.Firstly,the main preparation methods(laser processing,reactive ion etching)for the surface texture of ceramics are introduced.Secondly,the effects of the types(convex dot,pit,groove,bionic texture,etc.)and geometric parameters(width,depth,area ratio,etc.)of surface textures on the tribological properties of ceramics are discussed.Subsequently,the tribological mechanisms of surface texture under dry sliding and lubrication conditions are analyzed,respectively.In the condition of dry sliding,the surface texture can trap the wear debris and reduce the contact area between the ceramics and the counterbody;in the condition of lubrication,the surface texture can improve the hydrodynamic pressure and wettability of the ceramics during sliding,both of which can improve the tribological properties of the ceramics.Finally,the current challenges and future research directions of the surface texture of ceramics are summarized and prospected.
