Tribological behavior of hydrogenated W-C/a-C:H coatings deposited by three different sputtering techniques

Cerâmica
The evolution of structure, mechanical properties and friction behavior of DC magnetron sputtered (DCMS), high power impulse magnetron sputtered (HiPIMS) and high target utilization sputtered (HiTUS) W-C:H coatings was investigated as a function of the ...

A Physically Based Model for Non‐Point Source Pollutant Wash‐Off Process Over Impervious Surfaces

Water Resources Research, Volume 61, Issue 6, June 2025.
Abstract Physically based urban wash‐off modeling presents a promising approach for investigating the dynamics of road‐deposited sediments (RDS) and the associated pollutants during rainfall events. This paper proposes a novel physically based model to predict urban wash‐off process over impervious surfaces, where raindrop‐induced detachment, flow ...

Microstructure and mechanical properties of Al-Mg-Ti-B coatings prepared by high power impulse magnetron sputtering (HIPIMS) at room temperature

, 2017
In this work, Al-Mg-Ti-B coatings were synthesized at room temperature via high power impulse magnetron sputtering (HIPIMS). The as-deposited Al-Mg-Ti-B coatings exhibited a dense and X-ray amorphous microstructure.

Epitaxial growth of Cu(001) thin films onto Si(001) using a single-step HiPIMS process

Scientific Reports, 2017
We report on a new route to grow epitaxial copper (Cu) ultra-thin films (up to 150 nm thick) at ambient temperature on Si(001) wafers covered with native oxide without any prior chemical etching or plasma cleaning of the substrate.

Tailoring the Electrocatalytic Activity and Corrosion Resistance of CoCrFeNi and MnCrFeNi Thin Films by Anodization

Advanced Sustainable Systems, Volume 9, Issue 3, March 2025.
This work presents CoCrFeNi and MnCrFeNi thin films, synthesized by physical vapor deposition as bifunctional oxygen electrocatalysts that are corrosion‐resistant in alkaline conditions. After a detailed study of the film structure, the films are tested for oxygen catalysis and are active toward both oxygen evolution reaction (OER) and oxygen reduction

Bipolar HiPIMS kick‐pulse for high hardness in high‐entropy boride thin films

Journal of the American Ceramic Society, Volume 108, Issue 3, March 2025.
Abstract We report a microhardness indentation study for multicomponent refractory metal boride thin films that belong to the family of high‐entropy ceramics exhibiting superior hardness and high temperature properties. We focus on the nominally equimolar composition (Ti0.2Zr0.2Hf0.2Nb0.2Ta0.2)B2, which we refer to as HEB3, on c‐plane sapphire ...

Comparison on the superconducting properties of Nb and NbTiN thin films produced by both HiPIMS and bipolar HiPIMS

Most superconducting thin films found on SRF cavity are generally produced through magnetron sputtering using niobium (Nb) as target. Yet, this technique can still be improved as the resulting film lack in efficiency. Alternative materials such as NbTiN could potentially be used with significant improvement compared to pure Nb films.

Vysoká depoziční rychlost vrstev připravených reaktivní HiPIMS depozicí

, 2021
Teoretické modely naznačují, že při depozici vrstev pomocí reaktivního HiPIMS lze dosáhnout vyšší depoziční rychlosti v porovnání s pulzním magnetronovým naprašováním s vyššími opakovacími frekvencemi (Mf-PDCMS, mid-frequency pulsed dc magnetron ...

Direct metallization of polymers: The HiPIMS effect on early thin film growth

Nano Trends
The metallization of polymers is essential for developing flexible electronics, yet precise control over metal film growth remains challenging. This study demonstrates the effect of high-power impulse magnetron sputtering (HiPIMS) markedly influencing ...

Modelling of target effects in reactive HIPIMS

IOP Conference Series: Materials Science and Engineering, 2012
In reactive High Power Impulse Magnetron Sputtering (HIPIMS) of oxides, target effects such as reduced surface oxidation during pulse off time, increased implantation of reactive gas due to the higher discharge voltage as compared to normal DC sputtering, and enhanced target cleaning during on time are considered to be responsible for the differences ...
