Cutting Performance and Wear/Damage Characteristics of PCBN Tool in Hard Milling

open access: yesApplied Sciences, 2019
In the intermittent machining of hardened steel for the die and mold industry, determining how to reduce the wear of PCBN (Polycrystalline Cubic Boron Nitride) tools and improve their machining efficiency and quality is an important subject.

TiNx and TiOx/TiNx Barrier Layers for Al‐Based Metallization of Passivating Contacts in Si Solar Cells

open access: yesphysica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.
A Ti‐based diffusion barrier layer is presented for Ag‐free contacting of passivating contacts for crystalline Si‐based solar cells, enabling the use of standard screen‐printed Al‐paste. This approach provides an alternative to Ag‐based contact electrodes, while still maintaining high surface passivation quality and enabling low contact resistivity ...

Tribological properties of boron nitride synthesized by ion beam deposition [PDF]

open access: yes
The adhesion and friction behavior of boron nitride films on 440 C bearing stainless steel substrates was examined. The thin films containing the boron nitride were synthesized using an ion beam extracted from a borazine plasma.

Effect of two-step pretreatment on cobalt contents and surface roughness of tungsten carbide substrate prior to diamond coating [PDF]

open access: yes, 2010
Cemented tungsten carbide is the most widely used material for cutting tools. Due to extreme demands higher tool life several types of coating have been introduced to prolong the service time which include diamond coating.

Exceptionally strong phonon scattering by B substitution in cubic SiC

open access: yes, 2017
We use ab-initio calculations to predict the thermal conductivity of cubic SiC with different types of defects. An excellent quantitative agreement with previous experimental measurements is found.
