CERMET ALLOY BUILT ON TITANIUM CARBIDE AND METAL BINDER WITH MODIFIED SURFACE LAYER STRUCTURE Russian patent published in 2012 - IPC C23C14/30 C22C29/02 B82B3/00

Abstract RU 2459887 C1

FIELD: metallurgy.

SUBSTANCE: invention relates to cermet alloy of titanium carbide and nickel-chromium-aluminium binder (Ni-Cr-Al) with modified surface structure. The latter is produced by irradiating it by impulse super accurate electron beam in gas discharge nitrogen-bearing plasma. Said surface structural-phase component represents nanoparticles of titanium and aluminium nitrides. Said nanoparticles of titanium nitride feature mainly round shape and sizes of 50-100 nm while nanoparticles of aluminium nitride feature plate shape and sizes of 30-80 nm. Thickness of metallic binder melt surface layer at impulse effects of electron beam makes 50 mcm.

EFFECT: thermally stable surface structure, high strength in cutting metals.
