Abstract: Изобретение относится к различным областям машиностроения (тяжелое, транспортное, авиационно-космическое, автотракторное, энергетическое и т.д.) и может быть использовано для создания рабочих поверхностей элементов тяжелонагруженных узлов трения (например, подшипников качения и скольжения, кулачковых механизмов и т.д.). В заявке предлагается новый состав антифрикционного покрытия, обеспечивающего существенное повышение антифрикционных свойств смазанных узлов трения. Антифрикционное покрытие включает высокоориентированный граничный слой молекул смазочного материала и легированный молибденом слой наноструктурированного монокристаллического углерода толщиной 10-10м, который включает образовавшееся в процессе его нанесения повышенное количество адсорбционных центров, причем покрытие имеет монокристаллическую наноструктурированную линейно-цепочечную структуру. Повышение антифрикционных свойств достигается как за счет легирования молибденом, который в случае разрушения граничного слоя вследствие перегрузок в результате взаимодействия с серосодержащей смазочной средой образует в трибологическом контакте известную твердую смазку дисульфид молибдена, так и за счет наличия регулярного расположения адсорбционных центров, которые усиливают адсорбционные свойства углерода. 2 ил., 1 табл.
