摘要

对可持续润滑解决方案的追求促使人们大力研发符合绿色摩擦学原理的生物润滑剂，以减轻对环境的影响并提高工业效率。尽管如此，生物润滑剂在使用过程中也遇到了一些主要问题，如食品对相同植物油资源的竞争、原材料采购成本高昂以及纳米添加剂的应用困难等，这些都限制了生物润滑剂的使用范围。本综述探讨了生物润滑油生产的最新进展，重点是通过化学改性来提高植物油的热稳定性、抗氧化性和性能特征。此外，还研究了在生物润滑油中使用纳米颗粒作为纳米增强剂以减少摩擦和磨损的潜力。本文对纳米增强型生物润滑剂的摩擦学性能进行了评估，强调了它们在提高粘度、降低摩擦系数和改善耐磨性方面的功效。本文还认为，有必要提高生物润滑剂的纯度和分散性，使其性能更具经济可行性。最后，本文建议将生物润滑剂与石油基替代品相结合，并采用生态友好型纳米材料，以促进润滑剂制造的可持续发展，同时又不影响经济效益。

Green tribology assessment: A Comprehensive review of bio-lubricants and nano enhancers

The pursuit of sustainable lubrication solutions has led to significant research efforts in the development of bio-lubricants, aligned with green tribology principles, to mitigate environmental impact and enhance industrial efficiency. Nonetheless, the major setbacks such as food competing for the same vegetable oils resources, high costs of sourcing the raw materials, and difficulties in the application of nano additives have limited the extent of bio-lubricants usage. In this review, recent advancements in bio-lubricant production, focusing on chemical modifications to improve the thermal stability, oxidation resistance, and performance characteristics of vegetable oils are explored. Additionally, using nanoparticles as nano enhancers in bio-lubricants is examined for their potential to reduce friction and wear. The tribological performance of nano enhanced bio-lubricants is evaluated, highlighting their effectiveness in enhancing viscosity, reducing friction coefficients, and improving wear resistance. This paper also argues that it is necessary to improve the purity and dispersion of bio-lubricants to make them more economically viable for the performance. Finally, the incorporation of bio-lubricants with petroleum-based alternatives and implementation of eco-friendly nanomaterials is suggested to foster sustainable development in lubricant manufacturing without compromising economic aspects.
