PS-PVD Technology Landscape 2026 — PatSnap Eureka
Plasma Spray Physical Vapor Deposition Technology Landscape 2026
PS-PVD bridges conventional PVD and thermal spray by vaporizing oxide ceramics at chamber pressures of 50–500 Pa with plasma gun powers exceeding 50 kW. The process produces columnar, strain-tolerant coatings at deposition rates surpassing EB-PVD, with non-line-of-sight coverage of complex geometries.
PS-PVD: Bridging Thermal Spray and Vapor Deposition for Gas Turbine Coatings
PS-PVD operates at chamber pressures of 50–500 Pa — far below the 5,000–8,000 Pa range of conventional low-pressure plasma spray — with plasma gun powers typically exceeding 50 kW. Plasma jets expand to lengths up to 2,000 mm and diameters of 150–200 mm, with temperatures exceeding 6,000 K, enabling full vaporization of yttria-stabilized zirconia and other oxide ceramics.
Within the broader Very Low Pressure Plasma Spray (VLPPS) family, PS-PVD is distinguished by substantially higher plasma power and lower operating pressure than legacy LPPS/VPS processes. Coatings can be deposited from molten droplets, vapor phase, or a mixture, at deposition rates roughly an order of magnitude higher than conventional PVD, as documented in the foundational 2011 VLPPS review.
The core application domain is gas turbine thermal barrier coatings, where columnar YSZ structures provide strain tolerance during thermal cycling on turbine blades, vanes, and combustor liners. Environmental barrier coatings on SiC-SiC ceramic matrix composites represent the second major application cluster, with Rolls-Royce Corporation holding a concentrated active patent portfolio covering internal-cavity EBC deposition.

PS-PVD and VLPPS technologies are applied across four principal domains identified in this dataset, spanning gas turbine TBCs, CMC environmental barrier coatings, sputtering target and semiconductor-adjacent uses, and energy system components.
Gas Turbine Thermal Barrier Coatings
The dominant application in this dataset, PS-PVD deposits columnar YSZ coatings on turbine blades, vanes, and combustor liners to reduce heat flux into metallic substrates. The 2019 thermal stability study confirmed PS-PVD YSZ coatings retain metastable tetragonal phase after high-temperature exposure, validating commercial readiness. Sichuan Hangda New Materials’ 2022 CN active patent explicitly targets TBC manufacturing with plasma jets up to 2,000 mm at pressures of 5–200 Pa.
Thermal Spray CoatingCMC Environmental Barrier Coatings
Rolls-Royce Corporation’s patent family covers EBC deposition on SiC-SiC CMC substrates for next-generation gas turbine hot-section components, using operating pressures of 0.5–10 Torr (67–1,333 Pa) and plasma temperatures exceeding 6,000 K to vaporize metal silicate coating materials. The 2017 EP patent specifies metal silicate coatings with controlled silica content to protect CMC substrates from water vapor recession. The 2020–2021 active EP patents extend this to internal cavities where non-line-of-sight vapor-phase deposition is essential.
Environmental Barrier CoatingSputtering Target and Semiconductor Uses
A 2020 US patent by Ji, Helin describes a sputtering target preparation process using plasma spray technology, noting that the method produces high-density, high-purity targets comparable to initial powder purity — relevant to thin-film battery and semiconductor fabrication. A 2022 US patent from Shenyang Fortune Precision Equipment Co., Ltd. employs supersonic plasma spraying to deposit Y₂O₃ protective layers on semiconductor chamber components. These filings indicate plasma spray techniques adjacent to PS-PVD are entering semiconductor manufacturing workflows.
Semiconductor-AdjacentEnergy Systems and Power Generation
The 2017 energy technology review explicitly frames PS-PVD within efficiency-driven energy applications including solid oxide fuel cells and next-generation turbines, noting the process’s ability to deposit dense, thin coatings of 1–100 µm with controlled microstructure as directly applicable to electrochemical device fabrication. Recent literature from 2021–2022 compares PS-PVD and SPS columnar TBCs for automotive piston head applications and power generation turbines, broadening the addressable market beyond aerospace. Reactive VLPPS at ~150 Pa also enables in-situ titanium-titanium nitride composite coating synthesis for energy system wear applications.

Frequently Asked Questions: Plasma Spray Physical Vapor Deposition (PS-PVD)
PS-PVD operates at chamber pressures between approximately 50–500 Pa (0.5–5 mbar) — far below the 5,000–8,000 Pa range of conventional low-pressure plasma spray — with plasma gun powers typically exceeding 50 kW. These conditions produce plasma jets reaching lengths up to 2,000 mm and diameters of 150–200 mm, with temperatures exceeding 6,000 K.
PS-PVD produces columnar, strain-tolerant coatings structurally analogous to those produced by electron beam-PVD but at significantly higher throughput — deposition rates roughly an order of magnitude higher than conventional PVD. It also enables non-line-of-sight coverage of complex geometries, which is not feasible with EB-PVD.
In this dataset, Rolls-Royce Corporation holds the most concentrated active patent portfolio specifically focused on PS-PVD, with 3 active patents in EP jurisdictions (filed 2017–2021) all directed to EBC and internal-cavity coating on SiC-SiC CMC substrates for gas turbine components.
Reactive VLPPS (R-VLPPS) extends very low pressure plasma spray by introducing reactive gases such as nitrogen into the chamber at pressures around 150 Pa to synthesize composite coatings in-situ. A 2014 study confirmed titanium-titanium nitride composite coating feasibility at ~150 Pa. Within this dataset, reactive VLPPS is represented only by academic literature — no active patents have been identified, representing a potential filing opportunity.
