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

Abstract RU 2827204 C1

FIELD: ceramic compositions.

SUBSTANCE: invention relates to a composite ceramic material which can be used for making cutting tools and machine-building articles. Ceramic composite material for cutting tools includes alumina (α-Al₂O₃) and titanium carbide (TiC), and additionally contains titanium diboride (TiB₂) with the following ratio of components, wt.%: alumina (α-Al₂O₃) 22-24; titanium diboride (TiB₂) 37-39; titanium carbide (TiC) 38-40.

EFFECT: improved physical and mechanical characteristics of the composite ceramic material, namely increased bending strength, crack resistance and hardness.
