微纳米减摩自修复技术的研究进展及关键问题

Progress and key Issues of Micro-and Nanoscale Anti-friction Self-repairing Technology

阐述了微纳米减摩自修复材料的分类、作用机理及研究现状,提出目前微纳米减摩自修复技术发展中的关键问题是建立准确的自修复评价方法及评价指标;合理解决微纳米颗粒在油性介质中的分散与稳定难题;根据设备的润滑工况选择合适的材料及使用工艺;深入开展自修复机理研究,进而实现磨损尺寸自修复等。

Progress of the anti-friction self-repairing technology was summarized in details from three aspects about classifications, mechanisms and present status. Four key issues were also pointed out referring to the development of the technology at present. The first is to establish appropriate methods and criterions to evaluate efficacy of self-repairing; the second is to solve the problem of its dispersion and dispersive stability in oil medium; and the third is to choose suitable additives and operation processes according to different lubricating conditions. The last but not least is to investigate self-repairing mechanisms deeply. This will help worn surfaces to restore proper dimensions.
