摘要
在工件表面加工微/纳织构可以有效提高摩擦副的表面承载力,同时降低摩擦因数,减少摩擦磨损。通过微/纳织构的研究和发展现状,对微/纳织构的关键设计参数、加工方法、减摩机理以及微/纳织构与涂层结合技术进行了综合性阐述。其中,织构的形状、深度、深径比、面积率等都是影响摩擦磨损的重要参数;微/纳织构的加工技术中脉冲激光加工技术最具发展前景;根据织构在不同润滑状态下的减摩机理不同,可以应用于机械加工、生物医学等众多领域;将微/纳织构与涂层相结合可以提高涂层与刀具表面的结合力,进而提高刀具的切削性能、抗粘结磨损性能。最后,指出了在摩擦副表面织构及其对摩擦学性能影响的研究方面还存在的问题和研究前景。
Machining the micro/nano texture on the surface of the workpiece can effectively improve the surface bearing capacity of the friction pair,while reducing the friction coefficient,friction and wear.Through the research and development status of micro/nano texture,the key design parameters,processing methods,friction reduction mechanism and micro/nano texture combined with coating technology are comprehensively expounded.Among them,the shape,depth,aspect ratio and area ratio of the texture are important parameters which have an impact on the friction and wear;pulsed laser processing technology has the most development prospect in micro/nano texture processing technology;according to the different anti-friction mechanisms of texture under different lubrication conditions,it can be applied to many fields such as machining,biomedicine,etc;the combination of micro/nano texture and coating can improve the bonding force between the coating and the tool surface,thereby improving the cutting performance and anti-bonding wear performance of the tool.Finally,the problems and research prospects in the study of the texture of the friction pair surface and its influence on the tribological properties are pointed out.
