Laser ablation and processing of polycrystalline cubic boron nitride cutting tool material
The International Journal of Advanced Manufacturing Technology, 2021Laser ablation of polycrystalline cubic boron nitride (PCBN) material has been a great interest to cutting tool design and machining community due to distinct advantages offered by laser surface texturing on flank and rake surfaces of cutting tools for improved friction, reduced tool wear, and enhanced effectiveness of coolant application.

Granularity-induced plastic deformation mechanism of pure polycrystalline cubic boron nitride
Ceramics International, 2020Abstract Combined X-ray diffraction(XRD) profile analysis and HRTEM observation, a method for exploration of plastic deformation in pure polycrystalline cubic boron nitride (PcBN) samples with sizes of primary cBN powders was developed. XRD profile results showed that the coarse-grained PcBN exhibited a larger micro-strain e, a greater deformation ...

Abstract High-performance polycrystalline cubic boron nitride (PcBN) was sintered without binders at 1500 °C in a pressure range from 11 to 15 GPa using commercial micrometre cubic boron nitride (cBN) with a diameter of approximately 2–4 μm. The results demonstrated that the sample sintered at 12 GPa and 1500 °C had the best mechanical properties and

Thermal effects on tribological behaviors of polycrystalline cubic boron nitride
Ceramics International, 2021Abstract In order to understand the thermal damage mechanisms of polycrystalline cubic boron nitride (PcBN) under elevated temperature and the following influences on its tribological behaviors, the physicochemical characteristic of annealed PcBN under various temperatures was investigated by X-ray diffraction, Scanning electron microscopy and energy

Abstract The use of Raman spectroscopy, and in particular Raman line shifts, to measure stress in diamond and nitrides such as gallium nitride (GaN), is well known. In both diamond and GaN the application is principally to study stresses in thin films and at the substrate–thin film interface.

Properties and Performance of Polycrystalline Cubic Boron Nitride
International Journal of Applied Ceramic Technology, 2015Cubic boron nitride ( CBN ) is a lightweight (ρ = 3.45 g/cm 3 ) ceramic material that is harder than all materials except diamond. As harder ceramics tend to perform better as armor, this material is of interest to the military community.
