METHOD FOR OBTAINING COMPOSITE WEAR-RESISTANT COATING ON HARD-ALLOY TOOL Russian patent published in 2023 - IPC C23C28/00 C23C14/06 C23C14/24 C23C14/35 

Abstract RU 2803180 C1

FIELD: coating materials.

SUBSTANCE: method for producing a composite wear-resistant coating on a carbide tool in a vacuum. A layer containing a nanocrystalline phase and a matrix amorphous phase of silicon nitride Si3N4 is applied to a hard-alloy tool by vacuum-arc evaporation. Said nanocrystalline phase consists of TiAlSiN or TiCrAlSiN crystallites, wherein a layer of titanium diboride TiB2 with a thickness of 0.7-1.5 mcm is deposited on said layer by magnetron sputtering.

EFFECT: increased productivity of a hard-alloy tool.
