NANOSTRUCTURE OF REVITALISANT AND METHOD OF PRODUCTION OF SUSTAINABLE FORM OF NANOSTRUCTURE OF REVITALISANT Russian patent published in 2013 - IPC B22F9/16 B82B1/00 B82B3/00 

FIELD: nanotechnology.

SUBSTANCE: invention relates to nanotechnology and a method of production of nanomaterials that can be used in lubricant compositions for treatment of friction units, as well as for restoration of friction surfaces of the parts of mechanisms and machines. The nanostructured revitalisant is produced from dehydration products of natural and/or synthetic hydrates and/or their mixtures at a temperature of removal of constitutional water and the temperature of stabilisation of the dehydration product of 300-1200°C, with a stable form of nanostructure, which in a stable state has oxides of series MgO and/or SiO₂, and/or Al₂O₃, and/or CaO, and/or Fe₂O₃, and/or K₂O, and/or Na₂O and represents a two-phase granatum-shaped nanostructure consisting of binder phase, which volume size is 100-100000 nm, and grains which volume size is 2-2000 nm. To obtain the structured-nonrecoverable form an additional step of stabilisation of the dehydration product is performed at a temperature from 900 to 1200°C for 1-3 hours and perform an additional step of preparing a stable geometric form after feeding of the stabilised dehydration product on the friction surfaces and the friction area, when, depending on the mode of lubrication or friction mode, the following is set: h ≤ Ra ≤ of the size of stabilised nanostructure of the revitalisant, where h is the lubricating film thickness or the distance between the friction surfaces, and Ra is the surface roughness.

EFFECT: nanostructured revitalisant provides recovery of the friction surfaces, stabilisation of the surface layers of friction and minimisation of friction during the entire lifetime of the friction surfaces.
