M’Saoubi, Rachid ; Lenrick, Filip LU orcid and Bushlya, Volodymyr LU (2024) US20240228387A1
Abstract
A sintered polycrystalline cubic boron nitride (PCBN) body includes between 40 and 85 vol % of cubic boron nitride (cBN) particles and between 15 and 60 vol % of a binder phase. The binder phase has at least one metal oxide and at least one metal nitride. The metal oxide includes between 20 and 100 vol % of zirconium oxide (ZrO2) and up to 80 vol % of alumina (Al2O3) counted as a volume percentage of the total metal oxide content of the binder phase. The metal nitride includes aluminium nitride (AlN) and at least one metal nitride selected from the group consisting of vanadium nitride (VN), niobium nitride (NbN) and hafnium nitride (HfN). The content of the selected metal nitride selected is at least 10 vol... (More)
