Impacts of cubic Boron Nitride (CBN) support rods on TWT performance
2016 IEEE International Vacuum Electronics Conference (IVEC), 2016We 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 ...

Advanced Powder Technology, 2017
Abstract The Ti coatings on cubic boron nitride (cBN) grits were prepared by discharge treatment on a mixture of Ti powders and cBN grits in spark plasma sintering system. The uniform and full coatings with a thickness of ∼1.2 μm were prepared at 850 °C for 60 min, which were constituted with TiB2, TiN, and Ti phases.

Abstract Cubic boron nitride (CBN) composites are usually fabricated by sintering abrasive particles and binder powders under certain temperature and vacuum conditions. As a result, the inherent geometrical inhomogeneity of the abrasive grains in the binding matrix becomes an important intrinsic characteristic.

Nucleation, growth and characterization of cubic boron nitride (cBN) films
Journal of Physics D: Applied Physics, 2007Cubic 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).

Grinding of Steels with Cubic Boron Nitride (CBN)
CIRP Annals, 1984An 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 ...
