METHOD OF APPLYING GRAPHENE COATING ON METAL POWDERS Russian patent published in 2020 - IPC B22F1/02 

Abstract RU 2714151 C1

FIELD: technological processes.

SUBSTANCE: invention relates to application of nanodispersed two-dimensional carbon material graphene on particles of metal powders. Metal powder is mixed with carbon-containing component in form of liquid medium selected from group of acids: coal, carbonic acid, acetic, formic, or from a group of water-soluble salts: carbon, carbonic acid, acetic acid, formic acid, or from a group of chemical compounds containing carbon cations: CCl4, C8H10, C2H4Cl3. Mixing is carried out at temperature of liquid medium corresponding to decomposition temperature of carbon-containing component with provision of carbon extraction and its deposition on metal powders in the form of graphene layer.

EFFECT: obtaining uniform solid coating with isotropic properties at one stage at low temperatures.
