An Atomic‐Scale View at γ’‐Fe4N as Hydrogen Barrier Material
This study demonstrates the efficacy of γ’‐Fe4N nitride layers, formed via gas nitriding, as hydrogen permeation barriers. Advanced characterization, hydrogen permeation analysis, and DFT calculations reveal a 20 fold reduction in hydrogen diffusion at room temperature.

Effect of Post-Heat Treatment on the AISI M4 Layer Deposited by Directed Energy Deposition
Currently, high-speed steel (HSS) powders are deposited locally on a metal surface through direct energy deposition (DED) onto hardface tool steel. Although the HSS powder enhances the hardness and the abrasion resistance of a metal surface, it makes the

Formation of a Nanostructured Ti‐Si‐C‐N Coating by Self‐Organization with Reduced Amorphous Matrix
TiSiCN coatings are deposited by PECVD technique to investigate its micro‐ and nanostructure as well as its mechanical and thermal properties. Instead of a nanocomposite structure consisting of randomly oriented nc‐grains surrounded by an aa‐matrix, these TiSiCN coatings show much larger grains with (200) orientation.

Growth kinetics and wear resistance of vanadium carbide on AISI D2 steel produced by TRD process
Vanadium carbide coating was obtained on the surface of AISI D2 steel by thermal reactive diffusion process using molten borax as based salt and vanadium pentoxide as vanadium donor. The process was performed at 900 °C, 940 °C, 980 °C and 1020 °C for 3 h,
