Fractal Analysis of Micro Self-Sharpening Phenomenon in Grinding with Cubic Boron Nitride (cBN) Wheels [PDF]
, 2012 Self-sharpening phenomenon of the grain cutting edges during grinding is the main factor controlling the performance and the tool life of grinding wheels. Therefore, many studies on the relationship between the wear behavior and the self-sharpening of the grain cutting edges have been carried out (Yoshikawa, 1960; Tsuwa, 1961; Ichida et al., 1989, 1995;

Removal of sp2-boron nitride transition layer in the growth of cubic boron nitride films
, 2004 Practical application of cubic boron nitride (cBN) films is known to be hindered by its bad adhesion to substrates. One reason is that an sp2-bonded boron nitride (sp2-BN) transition layer is formed on the substrate surface at the early stage of ...

Curation and classification procedures for the UK Antarctic meteorite collection
Meteoritics &Planetary Science, Volume 59, Issue 12, Page 3215-3228, December 2024.Abstract The field of advanced curation is important for existing astromaterials collections, which includes samples returned by space missions, and meteorites and cosmic dust samples that have been recovered from here on Earth. In order to maximize the scientific return of the samples, contamination needs to be minimized at all stages of sample ...

Low energy kinetic threshold in the growth of cubic boron nitride films [PDF]
, 1994 We report the growth of cubic boron nitride (cBN) films by magnetron sputtering on Si (100) substrates. The films are grown in the presence of negative substrate bias voltages and a nitrogen plasma produced by an electron cyclotron resonance source.
