概要

Mo 2 NiB 2 -Ni cermets, one of the boride-base cermet, have been investigated as an alternative material to WC cemented carbides. By adding Cr and V to the Mo 2 NiB 2 -Ni cermet, the crystal structure of the Mo 2 NiB 2 is changed from orthorhombic type to tetragonal type, and mechanical properties show enhancement. However, details of structure deformation and the mechanical properties of Mo 2 NiB 2 phases still need to be discovered. In this study, we performed a nano indentation measurement to investigate the hardness of the Mo 2 NiB 2 phases. Cr and V doped complex boride base cermets with tetragonal structure-type and non-doped Mo 2 NiB 2 -Ni cermet with orthorhombic type structure were sintered using Reaction Boronising Sintering method proposed K. Takagi. According to the nano-indentation measurement, the hardness of the tetragonal phase exhibited 25 - 28 GPa, while that of the orthorhombic phase showed 20 - 23 GPa.
