Method for recovering cubic boron nitride abrasive grains from vitrified cBN stones – A preliminary study

Manufacturing Letters, 2021
Abstract In this work, a process is established for recovering cubic boron nitride (cBN) grains from fired vitrified cBN products. The abrasive grains are recovered by an acid washing technique. Two methods were used to recover the abrasive grains, namely with and without pre-heating.

Grinding of Steels with Cubic Boron Nitride (CBN)

CIRP Annals, 1984
An investigation is reported on grinding of steels with resin bonded cubic boron nitride (CBN) wheels with various operating parameters, wheel compositions, truing and dressing methods, and workpiece compositions and heat treatment. During grinding, the forces were generally found to decrease from extremely high peak values at a progressively slower ...

Nucleation, growth and characterization of cubic boron nitride (cBN) films

Journal of Physics D: Applied Physics, 2007
Cubic BN (cBN) has a set of extreme properties similar or even superior to diamond. The advance of science and technology of cBN has however been severely hampered by the poor quality of the material available (random orientation, limited film thickness, poor crystallinity and adhesion with substrates due to a non-cubic BN interlayer).

Determination of impurities in cubic boron nitride (cBN) by inductively coupled plasma mass spectrometry (ICPMS)

Diamond and Related Materials, 2022
Abstract The phase stability of cBN is critically dependent on the content and amount of impurities present. While studies have shown qualitatively that the addition of certain impurities can either increase or decrease the cBN-hBN phase transition temperature, studies have yet to show this effect quantitatively. This is because analytical methods to

Impacts of cubic Boron Nitride (CBN) support rods on TWT performance

2016 IEEE International Vacuum Electronics Conference (IVEC), 2016
We propose new support rod material in helix TWTs to improve the heat dissipation performance of the tubes, which is the cubic Boron Nitride (CBN) crystal with the second highest thermal conductivity and relatively low dielectric constant. The high frequency characteristics and the beam-wave interaction of helix slow wave structure with CBN and BeO ...

Photoluminescence spectroscopy of electron‐irradiation induced defects in cubic boron nitride (cBN)

physica status solidi (c), 2004
Cubic boron nitride is an ultra-hard material that is widely used in industrial applications where its specific mechanical properties make it the material of choice. Compared to diamond, which has similar applications, relatively little is known about the defects in cBN, their structure, electronic properties and their possible effects on the ...

Machinability of Pearlitic Cast Iron With Cubic Boron Nitride (CBN) Cutting Tools

Journal of Manufacturing Science and Engineering, 2002
In order to increase the accurate finishing productivity of pearlitic cast iron, face milling by CBN (Cubic Boron Nitride) cutting tools was studied. The main focus of the study is the machinability investigation of pearlitic cast iron with CBN cutting tools by studying the relationships among machining conditions such as feed rate, cutting speed as ...

Polycrystalline cubic boron nitride sintered compacts prepared from nanocrystalline TiN coated cBN powder

Materials Science and Engineering: A, 2012
Abstract Polycrystalline cubic boron nitride (PcBN) samples were fabricated via high pressure high temperature (HPHT) sintering process using nanocrystalline TiN particle coated cBN powder. cBN powder was coated with TiN nanoparticles prior to sintering for the purpose of improving microstructural homogeneity.
