| 面向环境保护和资源节约使用的呼声，应用少量润滑剂实现摩擦表面定域可控润滑的研究越来越受到关注。基于润滑剂定域润滑效应，从定域润滑的形成机制、润滑层结构、润滑种类、润滑效果和定域与微观-宏观域关联等角度进行探索研究。概述了近年来国内外关于定域润滑的研究进展，从润滑约束角度概述了外力约束型、空间封闭约束型、表面形貌约束型和表面物化约束型等不同形式的定域润滑，同时对其成因及润滑机理进行了阐述，并对不同约束方式之间的耦合润滑效果研究，得出不同定域因素间会产生影响，且作用效果相似的约束方式之间耦合影响会明显增强。此外，系统性地阐述了定域润滑在数学模型理论研究、实验研究、仿真分析等方面研究的发展概况，并分析了定域润滑在摩擦过程中的润滑效应及其优势与不足。最后分析了目前定域润滑研究中存在的问题和拓展方向，并提出其可在多种影响因素耦合方面重点研究的建议。 |

| In response to calls for environmental protection and the economical use of resources, research into the application of small amounts of lubricant to achieve controlled lubrication of friction surfaces in a defined area has received increasing attention. This paper is based on the lubrication effect of fixed domain lubricant, from the formation mechanism of fixed domain lubrication, lubrication layer structure, lubrication type, lubrication effect and the correlation between fixed domain and micro-macro domain. This paper explores the formation mechanism, lubrication layer structure, lubrication type, lubrication effect and micro-macro domain correlation of fixed domain lubrication, analyses the performance of fixed domain lubrication in various aspects and its application, outlines the research progress on fixed domain lubrication at home and abroad in recent years, outlines different forms of fixed domain lubrication such as external force constrained, space closed constrained, surface morphology constrained and surface materialization constrained from the perspective of lubrication constraint, at the same time, the causes and lubrication mechanism are explained. The external force constraint type can achieve external control of lubrication effect; the space closed constraint type has mature technology, low cost, stable and widely used; the surface morphology constraint type forms a more accurate space of the fixed domain, does not affect the part outside the lubrication area. The surface materialisation constraint type has a good effect on the surface protection of the friction substrate, and is suitable for a variety of materials, and can reconfigure the molecular arrangement at the microscopic level, which has a broad research prospect. In this paper, the effect of coupling lubrication between different constraint types is investigated, and it is concluded that the effect of coupling between different fixed-domain factors can be influenced, and the effect of coupling between constraint types with similar effects can be significantly enhanced. The influence of single and multiple factors on lubrication performance and optimum parameters is demonstrated by analysing the corresponding experiments. In addition, this paper systematically illustrates the development overview of the research on fixed-domain lubrication in terms of mathematical model theory research, experimental research and simulation analysis, explores the influencing factors of fixed-domain lubrication from different research approaches, and analyses the lubrication effect of fixed-domain lubrication in friction processes and its advantages and shortcomings from practical applications, especially illustrates the coupling analysis of fixed-domain lubrication from macroscopic to microscopic levels, proposes the fixed-domain lubrication The analysis at the microscopic level points out that molecular arrangement and molecular forces also have some influence on fixed-domain lubrication; finally, the problems and feasible directions for expansion in the current research on fixed-domain lubrication are analysed, and suggestions for its focus on the coupling of multiple influencing factors are put forward. The study not only contributes to the study of the mechanism of fixed-domain lubrication, but also facilitates the expansion and improvement of the theory in the field of full-domain lubrication, which has a wide range of promising applications in reducing friction and wear and improving lubrication effect, and is of great help in reducing resource use and environmental pollution. |
