Over the last few years, interest in applications of nanoparticles as lubricant additives has steadily grown due to the demonstrated reduction in friction and wear of nanoparticle-containing lubricant formulations (so-called nanolubricants). Particularly, studies of motor oils containing a “green” all-carbon additive, detonation nanodiamond (DND) particles, revealed their positive impact on the performance of lubricant compositions and fuel economy in engine tests. In the current review we discuss critical issues toward successful implementation of DND in nanolubricants: role of DND structural characteristics, stability of colloids of DND in oils, DND compatibility and synergism with other additives in commercial oils, mechanisms of DND impact on the properties of lubricants. Owing to the abrasive nature of diamond, DND-based nanolubricants must be carefully engineered in order to avoid increased wear of the friction surfaces and get full benefit from significantly reduced friction of well-polished surfaces.

在过去的几年中，由于已证明减少了含纳米颗粒的润滑剂制剂（所谓的纳米润滑剂）的摩擦和磨损，因此对将纳米颗粒用作润滑剂添加剂的兴趣稳步增长。特别是，对包含“绿色”全碳添加剂，爆轰纳米金刚石（DND）颗粒的机油的研究表明，它们在发动机测试中对润滑剂组合物的性能和燃油经济性具有积极影响。在当前的综述中，我们讨论了DND在纳米润滑剂中成功实施的关键问题：DND结构特征的作用，DND胶体在油中的稳定性，DND的相容性以及与市售油中其他添加剂的协同作用，DND对润滑剂性能的影响。由于钻石具有磨蚀性，
