Description
Summary:The goal of this work is to develop the wear-resistant composites of titanium nitride-AlN system with a high level of physicomechanical properties. The titanium nitride-AlN (at the mol.content 1:3, 1:1 and 3:1) compact samples were prepared by the powder metallurgy methods. The peculiarities of their sintering under pressure were studied in order to obtain the fine-grain structure with a homogeneous phases distribution. The structure and phase composition of ceramics were investigated with the aid of XRD and SEM methods. The physicomechanical properties, viz., hardness HRA, bending strength, and toughness coefficient, were defined. It is established that the titanium nitride-AlN ceramics (1:3 and 3:1) have a high level of properties: sigma sub bend 0=760-600 MPa; H sub v 0=26-27 GPa; HRA=89.5; toughness coefficient -9-12 MPa m exp 1/2 . The ceramics developed can be used as performance materials.
