Обзор посвящен современному состоянию исследований и достижений в области модифицирования смазочных материалов. Для улучшения трибологических характеристик смазок используют различные добавки,  в частности, наночастицы. Такие добавки позволяют избежать прямого контакта, снижают коэффициент трения  и износ. Учитывая, что графен значительно повышает трибологические характеристики смазок, в обзоре рассмотрены основные способы его получения. Показано, что наиболее перспективной технологией получения графена для модифицирования смазочных материалов является жидкофазная сдвиговая эксфолиация кристаллического графита, поскольку масляные смеси с нанопластинами равномерно распределяются в  пластичной смазке и обеспечивают ее стабильную работу в парах трения. Рассмотрен вариант смешения нанопластин графита с пластичной смазкой в роторном диспергаторе. Показано, что наряду с повышением трибологических характеристик, смазка, модифицированная нанопластинами графита, создает антифрикционную пленку на поверхностях трения. Проанализированы составы антифрикционной пленки и результаты ее использования. Намечены пути совершенствования технологии модифицирования пластичных смазок нанопластинами графита. В первую очередь необходимо модернизировать основное оборудование: барабанную стержневую мельницу; узел классификации графеносодержащих суспензий по размерам нанопластин; роторный диспергатор. Учитывая, что максимальный эффект наблюдается при использовании антифрикционной пленки + смазка, модифицированная нанопластинами графита, необходимо детально исследовать процесс формирования антифрикционной пленки и определить ее оптимальное содержание в смазке.

The review is devoted to the current state of research and achievements in the field of modification of lubricants. To improve the tribological characteristics of lubricants, various additives, in particular, nanoparticles, are used. These additives avoid direct contact, reduce friction and wear. Given that graphene significantly improves the tribological characteristics of lubricants, the main methods for its production are considered. It is shown that the most promising technology for obtaining graphene to modify lubricants is liquid-phase shear exfoliation of crystalline graphite, since oil mixtures with nanoplates are evenly distributed in grease and ensure its stable operation in friction pairs. A variant of mixing graphite nanoplates with grease in a rotary disperser is considered. It is shown that, along with an increase in tribological characteristics, the lubricant modified with graphite nanoplates creates an antifriction film on friction surfaces. The compositions of the antifriction film and the results of its use are analyzed. The ways of improving the technology of modifying greases with graphite nanoplates are outlined. First of all, it is necessary to modernize the main equipment:  a drum rod mill; node for classifying graphene-containing suspensions according to the nanoplates size; rotary disperser. Considering that the maximum effect is observed when using an antifriction film + grease modified with graphite nanoplates, it is necessary to study in detail the antifriction film formation and determine its optimal content in the lubricant.
