Development prospects of the cutting material on ТiB₂—TiN composition basis

Abstract

Urgency of TiB₂—TiN composition use as cutting material due to high mechanical properties, oxidation resistance, frictional properties and wear resistance was proved. Heat conductivity of TiB₂—TiN ceramics exceeded considerably heat conductivity of ОНТ-20 (кортинит), РК-30 (силинит-Р) ceramics which have been produced. The tests which have been conducted in LTD "Virial"(Saint Petersburg) showed possibility of TiB₂—TiN composition use for faceted cutting inserts making by application of FAST sintering method.
