摘　　要：轴向柱塞泵是液压传动系统的核心动力元件,广泛应用于诸多工程领域。滑靴副是轴向柱塞泵中3对关键摩擦副(滑靴副、配流副和柱塞副)之一,显著影响柱塞泵的服役安全。滑靴副的磨损是引起柱塞泵失效的主要原因,开展滑靴副的服役损伤与防护措施研究对柱塞泵向高速、高压化技术发展有着重要意义。概述了轴向柱塞泵的基本工作原理;介绍了滑靴副间隙润滑油膜的形成和3大作用(润滑、密封和承载),以及油膜特性测量方法和影响因素;阐述了滑靴副的磨损机理、磨损影响因素及磨损状态评估方法;基于滑靴副的油膜特性及磨损机理,着重讨论了滑靴副延寿设计方法和失效防护措施,如优化滑靴副材料匹配、结构的延寿设计方法,以及利用表面织构化、固体润滑涂层改善滑靴副表面摩擦学性能的表面改性方法。表面织构化的原理是利用微纳米加工手段在滑靴副材料表面加工出具有一定形状、尺寸且排列规则的几何阵列来收集磨屑、储存润滑介质或通过产生流体动压效应来增强润滑进而减小磨损,固体润滑涂层则是通过改变基体表面的组织结构来提高滑靴副表面的承载力和增强滑靴副的自润滑性能。最后对轴向柱塞泵滑靴副未来的研究方向提出了展望。As a pivotal power unit in the hydraulic transmission system,the axial piston pump plays an important role in numerous engineering fields.Slipper-swashplate pairs are one of the three key friction pairs(slipper-swashplate pairs,cylinder-valve plate pairs,and piston-cylinder pairs)in axial piston pump,which significantly affects the service safety of piston pump.The wear of slipper-swashplate pairs is the main reason for the failure of piston pump.It is of great significance to study the service damage and protection measures of slipper-swashplate pairs for the development of piston pump to high speed and high pressure technology.In this review,the basic working principle of axial piston pump was firstly presented in brief.Secondly,the formation and three functions(lubrication,sealing and bearing)of the lubricating oil film in the clearance of slipper-swashplate pairs as well as the measurement method and affecting factors of oil film characteristics were systematically elaborated.Then,the wear mechanism,wear affecting factors and wear state evaluation method of slipper-swashplate pairs were expounded.Based on the oil film characteristics and wear mechanism of slipper-swashplate pairs,the design method for life extension and failure protection measures of the slipper-swashplate pairs were emphatically explored,such as the design method of optimizing the material matching and prolonging the life of the slipper-swashplate pairs,and the surface modification method of improving the tribological properties of the slipper-swashplate pairs surface by surface texturing and solid lubrication coating.Surface texturing was to process a geometric array with a certain shape,size and regular arrangement on the surface of the slipper-swashplate pairs material by micro-nano machining means to collect wear debris,store lubricating medium or produce hydrodynamic effect to enhance lubrication and reduce wear,while solid lubrication coating improved the bearing capacity of the slipper-swashplate pairs surface and enhanced the self-lu
