Wear of polycrystalline boron nitride tool during the friction stir welding of steel [PDF]

, 2018
The wear issue of a polycrystalline boron nitride (PCBN) tools during the friction stir welding of two grades of steel, DH36 and EH46, was studied. Two welding traverse and tool rotational speeds were used when welding the DH36 steel.

Reaction sintering of polycrystalline cubic boron nitride at high pressure and temperature.

Journal of the Japan Society of Powder and Powder Metallurgy, 1989
Single phase sintered compact of cBN (polycrystalline cBN) may be prepared under high pressure and temperature (>5.2GPa, >1350°C) from hBN compact carrying a small amount of Mg3BN3 as a catalyst. This work investigated the influence of the amount of Mg3BN3 added to the hBN compact on the microstructure and the thermal conductivity of the prepared ...

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Wear-adaptive optimization of in-process conditioning parameters during face plunge grinding of PcBN

Scientific Reports, 2022
Polycrystalline cubic boron nitride is a very hard material. Machining of this material is performed by grinding with diamond tools. Due to its high hardness, grinding tools are subjected to severe microscopic and macroscopic tool wear.

Optical Properties of BN in the cubic and in the layered hexagonal phases

, 2001
Linear optical functions of cubic and hexagonal BN have been studied within first principles DFT-LDA theory. Calculated energy-loss functions compare well with experiments and previous theoretical results both for h-BN and for c-BN.

High‐Pressure Synthesis and Chemical Bonding of Mg3BiN

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The anti‐perovskite Mg3BiN is obtained by high‐pressure high‐temperature reaction of Mg–Bi mixture with boron nitride serving as crucible material. The compound is electron precise with essentially ionic bonding, and DOS calculations indicate semiconducting behavior.

In Situ Observations during Chemical Vapor Deposition of Hexagonal Boron Nitride on Polycrystalline Copper. [PDF]

, 2014
Using a combination of complementary in situ X-ray photoelectron spectroscopy and X-ray diffraction, we study the fundamental mechanisms underlying the chemical vapor deposition (CVD) of hexagonal boron nitride (h-BN) on polycrystalline Cu.
