METHOD FOR POLISHING CYLINDRICAL SURFACE OF POLYCRYSTALLINE DIAMOND COATING OF COMPONENTS Russian patent published in 2023 - IPC B24B1/00 

FIELD: coatings.

SUBSTANCE: method for surface treatment of polycrystalline diamonds obtained by chemical vapour deposition, and can be used for production of components for fuel equipment of internal combustion engines and many other products operating under increased friction and wear. The method for polishing a polycrystalline diamond coating on a cylindrical surface of a component involves imparting rotation and transverse feed to a tool in the form of a metal brush made of a material chemically active in relation to diamond, and rotation and reciprocating motion – to the component. At the final stage of processing, the rotation speed of the tool is reduced by 2-3 times compared to the initial one speed.

EFFECT: quality of the treated surfaces of the components is improved, and metal sticking to the coating surface is prevented.
