COMPOSITE CERAMIC MATERIAL FOR CUTTING TOOLS Russian patent published in 2024 - IPC C04B35/58 C04B35/56 C04B35/117

Abstract RU 2827754 C1

FIELD: manufacture of composite ceramic material.

SUBSTANCE: invention relates to the manufacture of a composite ceramic material that can be used for the manufacture of cutting tools and machine-building products. Ceramic composite material for cutting tools, including alumina (α-Al₂O₃) and titanium carbide (TiC), additionally contains titanium diboride (TiB₂) at the following component ratio, wt.%: alumina (α-Al₂O₃) 15-20; titanium carbide (TiC) 19-22; titanium diboride (TiB₂) 61-64.

EFFECT: technical result is an improvement in the physical and mechanical characteristics of the composite ceramic material, namely, an increase in bending strength, crack resistance and hardness.
