Preparation and Characterization of Al2O3/h-BN Composite Coatings by Atmospheric Plasma Spraying (APS)

Crystals
To improve the adhesion strength of polymer functional films, corona treatment is required. Corona rollers are key components for corona treatment, which are used in high-voltage electric fields for a long time. In this work, in order to improve electrical insulation, arc resistance, wear resistance, and chemical stability, a coating is usually sprayed

Eu3+ as a structural probe in yttrium silicates through photoluminescence emission spectra

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract This work presents the first steps in using Eu3+ as a structural probe using photoluminescence (PL) emission spectra. The sol–gel synthesis of four Eu3+‐doped powders encompassing seven phases of the yttrium silicate phase system is detailed.

A Comparative Study on Ni-Based Coatings Prepared by HVAF, HVOF, and APS Methods for Corrosion Protection Applications

, 2016
Selection of the thermal spray process is the most important step towards a proper coating solution for a given application as important coating characteristics such as adhesion, and microstructure, etc. are highly dependent on it. In the present work, a

Effects of thermal spray processes on the development microstructure and thermal properties of NiCrAlY bond coats deposited over superni C-263 aero engine combustor liner alloy

Materials Research Express
Thermal barrier coatings need extremely durable and suitable bond coats to survive in high temperature environments. Ceramic top coat spallation is a significant problem in TBCs, which occurs mainly due to high temperature corrosion, thermally grown ...

Development of HA/Ag-NPs Composite Coating from Green Process for Hip Applications

Molecules, 2017
In the present study, biological hydroxyapatite (HA) was obtained from bovine bones through a thermal process. A total of 0% and 1% of silver nanoparticles (Ag-NPs) synthesized from Opuntia ficus (nopal) were added to the biological hydroxyapatite ...

Synthesis, Properties, and Typical Applications of MXene‐Based Heterostructure Materials

Advanced Materials Interfaces, Volume 12, Issue 19, October 6, 2025.
In recent years, MXene‐based heterostructure materials have achieved fruitful outcomes in multiple aspects. However, a comprehensive and systematic summary of MXene‐based heterostructures is still absent. This review summarizes the performance characteristics, synthesis methods, and the latest research progress of MXene heterostructures in several ...

Understanding the residual stress distribution through the thickness of atmosphere plasma sprayed (APS) thermal barrier coatings (TBCs) by high energy synchrotron XRD; digital image correlation (DIC) and image based modelling

Acta Materialia, 2017
esidual stresses are considered to be the driving forces for the in-service failure of TBCs. The residual stress distribution through an APS TBC has been experimentally measured by high energy synchrotron X-ray diffraction (XRD) showing two distinct features. Firstly a discontinuity or ‘jump’ in the residual stress trend at a depth of approximately 100

Novel Fe‐Modulating Raney‐Ni Electrodes toward High‐Efficient and Durable AEM Water Electrolyzer

Advanced Energy Materials, Volume 15, Issue 38, October 14, 2025.
Plasma spray (APS) is used to fabricate Fe‐modulated Raney‐Ni bifunctional electrodes for AEMWE. The resulting NFA‐CA exhibits distinct core–shell NiFe‐NiFe hydroxides, enabling 2 A cm⁻2 at 1.79 V—surpassing the U.S. Department of Energy's target for AWE systems—and demonstrates excellent durability with 1000 hours of stable operation at 1 A cm⁻2 ...
