BORIDE/ZIRCONIUM OXIDE/TITANIUM CARBONITRIDE-BASED CERAMIC MATERIAL HAVING HIGH TOUGHNESS

摘要

PURPOSE:To provide a metal boride-based ceramic having mechanical and thermal properties enabling the wide use as an abrasion-resistant tool or cutting tool to be used at a high temperature. CONSTITUTION:The objective ceramic material can be produced by forming and sintering a powdery mixture of 20-88wt.% (based on the total mixture) of one or more kinds of powdery metal boride, 10-50wt.% of monoclinic zirconium oxide powder and 2-70wt.% of Ti(C, N).
