Plasma characteristics and coating microstructures of yttria stabilized zirconia during plasma spray physical vapor deposition

2017 14th International Bhurban Conference on Applied Sciences and Technology (IBCAST), 2017
Plasma spray physical vapor deposition (PS-PVD) is a promising technique used to manufacture strain tolerant and non-line-of-sight thermal barrier coatings (TBC). It bridges the gap between conventional plasma spraying and electron beam physical vapor deposition (EB-PVD).

Development of Porous YSZ Coatings with Modified Thermal and Optical Properties by Plasma Spray Physical Vapor Deposition

open access: yesJournal of Solid Mechanics and Materials Engineering, 2010
Porous and feather-like yttria-stabilized zirconia coatings have been deposited by plasma spray physical vapor deposition (PS-PVD) at the deposition rate of around 200 µm/min. The porosity of the coating reached > 50% and the overall thermal conductivity was reduced less than 0.5 W/mK, both of which were fundamentally independent of the coating ...

A promising non-transformable tetragonal YSZ nanostructured feedstocks for plasma spraying-physical vapor deposition

Ceramics International, 2018
Abstract The nanostructured 8 wt% yttria stabilized zirconia (n-8YSZ) feedstocks used for plasma spraying-physical vapor deposition (PS-PVD) were successfully prepared by the powder reconstitution method for the first time in this study. The n-8YSZ feedstocks were characterized by TEM, SEM and XRD.

A TEM Investigation of Columnar-Structured Thermal Barrier Coatings Deposited by Plasma Spray-Physical Vapor Deposition (PS-PVD)

Plasma Chemistry and Plasma Processing, 2018
The plasma spray-physical vapor deposition technique (PS-PVD) is used to deposit various types of ceramic coatings. Due to the low operating pressure and high enthalpy transfer to the feedstock, deposition from the vapor phase is very effective. The particular process conditions allow for the deposition of columnar microstructures when applying thermal

Preparation and Distribution Analysis of Thermal Barrier Coatings Deposited on Multiple Vanes by Plasma Spray-Physical Vapor Deposition Technology

Journal of Engineering Materials and Technology, 2017
The multicomponent NiCoCrAlTaY coating as bond layer as well as the zirconia stabilized by yttrium oxide (YSZ) coating as top ceramic layer was deposited on duplex vane surface by plasma spray-physical vapor deposition (PS-PVD) system. The thickness and microstructure of thermal barrier coatings (TBCs) under the influence of duplex vane geometry were ...

Performance Comparison of Atmospheric Plasma Spraying and Plasma Spraying Physical Vapor Deposition for Environmental Barrier Coatings

International Thermal Spray Conference
Abstract The commonly used method for preparing EBCs is atmospheric plasma spraying (APS), but it has problems such as easy oxidation of the coating, low spraying power, and low substrate temperature, resulting in the coating having multiple pores, cracks, and insufficient density.
