SYNTHESIS OF SOLID ELECTROLYTES BASED ON ZrO2 BY ATMOSPHERIC PLASMA SPRAYING [PDF]

open access: yes, 2023
This article describes the synthesis of a coating based on zirconium dioxide, with a different content of stabilized yttrium oxide, by atmospheric plasma spraying to obtain solid electrolytes. Phase composition, structure, stability and durability depend

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Contamination Particles and Plasma Etching Behavior of Atmospheric Plasma Sprayed Y2O3 and YF3 Coatings under NF3 Plasma

open access: yes, 2019
Yttrium oxide (Y2O3) and yttrium oxyfluoride (YO0.6F2.1) protective coatings were prepared by an atmospheric plasma spraying technique. The coatings were exposed to a NF3 plasma.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Atmospheric Plasma Spraying of Different MgO/Al2O3 Feedstocks

open access: yesJournal of Thermal Spray Technology, 2023
AbstractNine commercial and experimental powders from the MgO/Al2O3 system have been investigated in the present project. The composition ranged from MgO/MgAl2O4 composites with more than 70% MgO to an alumina-rich spinel powder (94% Al2O3). The powders were fused and crushed or agglomerated and sintered.

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

open access: yesAdvanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

A model of the interface between plasma jet simulation and the simulation of coating formation during atmospheric plasma spraying (APS)

open access: yes, 2004
The atmospheric plasma spraying (APS) process can be divided into sub-processes, which are simulated by different numerical methods. The balance equations of momentum, mass and energy of the plasma jet are solved numerically by applying the finite volume
