Lubricant composition and method for production thereof

Изобретение относится к смазочному составу, включающему смазочную среду и продукт дегидратации гидратов природных минералов или смеси природных минералов, или синтезированных гидратов, в котором продукт дегидратации, включающий оксиды MgO, и/или SiO2, и/или Al2O3, и/или СаО, и/или Fe2O3, и/или K2O, и/или Na2O, получен после удаления конституционной воды и разрушения кристаллической решетки при температуре от 350 до 900°С. Смазочный состав характеризуется тем, что продукт дегидратации получен после удаления конституционной воды и разрушения кристаллической решетки при температуре не более 900°С и достигает устойчивой и/или безвозвратной фазы при температурной выдержке в диапазоне 900-1200°С, что обеспечивает получение наноструктуры продукта дегидратации в диапазоне 100-100000 н.м. Также изобретение относится к способу приготовления указанного смазочного состава. Технический эффект при использовании смазочного состава основан на том, что первоначальный размер нанообразований ревитализанта сопоставим по масштабу с размерами дефектов поверхности (зернистость, микрошероховатость). Такое взаимодействие приводит к пластической деформации металла в нанообъемах и переводу в активное наноструктурированное состояние поверхностного слоя. При этом происходит интенсивное дробление зерен металла, увеличение плотности их границ, улучшаются условия для диффузии углерода вглубь поверхности (по вертикали) и внутрь зерен (по горизонтали). 2 н.п. ф-лы, 12 табл., 12 пр.
