中文摘要:
      表面织构技术是一种加工方便且不破坏材料本质的表面改性方法,在材料表面加工出具有一定形状和规则的微观结构以改善材料的表面摩擦性能。但不同工况条件下影响摩擦性能的可变因素太多,以至于无法得到各设计参数的最优通用方案。从提出附加流体动压效应到表面织构形貌、尺寸、深度、面积占有率、坑底形状、取向和分布形式等方面,回顾了国内外表面织构减摩作用的研究发展历程。概述了凹陷织构中连续织构和离散织构的表面形貌对材料表面摩擦特性的影响,并在离散织构中重点分析了三角形、矩形、菱形、六边形、椭圆形、圆柱形、球形、水滴形、圆环形、雪花形和葫芦形等织构形貌对材料表面摩擦特性的影响;论述了各几何参数中织构直径和面积占有率对摩擦因数的影响比织构深度大;阐述了不同分布形式的表面织构对摩擦特性的影响;在干摩擦、边界润滑、流体润滑和混合润滑等4种状态下,总结了不同工况条件下表面织构的减摩机理,并对表面织构存在的问题提出建议,以期为表面织构的研究者提供参考。
英文摘要:
      Surface texture technology is a kind of surface modification method which is convenient to process and does not destroy the essence of materials. The surface texture technology processes the surface of the material with a certain shape and regular microstructure to improve the surface friction properties of the material. However, there are too many variable factors that affect the friction performance under different working conditions, so that the optimal general scheme of each design parameter can not be obtained. In this paper, the research and development of antifriction effect of surface texture at home and abroad is reviewed from the introduction of additional hydrodynamic pressure effect to the morphology, size, depth, area share, pit bottom shape, orientation and distribution of surface texture. In this paper, the effects of surface texture morphology, geometric parameters and distribution on its tribological properties are discussed respectively. The morphology of surface texture is divided into protruding texture and concave texture, in which protruding texture is mainly used to increase friction coefficient and hydrophobicity, while sag texture is generally used to reduce friction coefficient and reduce the resistance of sliding process. In engineering, in order to improve the service life of parts, the sunken texture which can reduce the friction coefficient and improve the friction performance is generally adopted. This paper focuses on the influence of the surface texture morphology of continuous texture and discrete texture on the surface friction properties of materials in concave texture. Continuous texture is an efficient means of drag reduction, and its advantage is that it is convenient for processing. At the same time, it is also better than discrete texture in absorbing fine debris. Under good lubrication conditions, wear debris is easy to move in the grooves of continuous texture, which can effectively prevent a large number of wear debris from filling texture and causing texture failure. The discrete texture with reasonable arrangement of pit texture can store the shedding wear particles in the process of sliding, reduce the contact area and solve the problem of lack of oil. At present, the excellent performance of discrete texture in lubrication and wear reduction has attracted wide attention of researchers at home and abroad. There are the most kinds of morphologies of discrete texture, and the research on it is the most detailed. In the discrete texture, the effects of triangle, rectangle, diamond, hexagon, ellipse, cylinder, sphere, water drop, ring, snowflake and gourd texture on the friction properties are analyzed. As for the geometric parameters of surface texture, this paper discusses that among the geometric parameters, the influence of texture diameter and area share on the friction coefficient is greater than the depth of texture, in which the size of texture has a great influence on the lubrication performance of friction pairs. Too large and too small size are not conducive to the advantage of micro-texture, or even cause negative effects. As for the distribution of surface texture, this paper expounds the influence of different distribution forms of surface texture on the friction properties. The antifriction mechanism of surface texture under different working conditions is summarized under four lubrication conditions of dry friction, boundary lubrication, fluid lubrication and mixed lubrication, and some suggestions on the existing problems of surface texture are put forward. It is expected to provide a reference for the researchers of surface texture. In the future, based on the application of surface texture in traditional manufacturing, surface texture will gradually expand to many new fields.
