VPS 3000 Vacuum Plasma Spray System

Name: VPS 3000 Vacuum Plasma Spray System
Brand: GST
SKU: VPS3000
Price: 1800000 USD
Availability: MadeToOrder

Hardware warranty 12 months

The VPS 3000 is an advanced vacuum plasma spray system for coating processes that require a controlled low-pressure, inert atmosphere. By evacuating the process chamber and then establishing an argon atmosphere, the system reduces the influence of reactive gases during spraying and helps protect heated coating particles from oxidation.

All characteristics

This controlled environment is intended for demanding coating applications where purity, density, adhesion, substrate preparation, and repeatability are critical. The VPS 3000 combines a digital Process Control Center, GST MCoat™ software, vacuum-chamber process monitoring, automated workpiece and torch manipulation, powder feeding, cooling supervision, and comprehensive safety interlocks.

Each VPS 3000 is engineered around the customer’s workpiece dimensions, chamber requirements, coating material, throughput, vacuum requirements, plasma gun configuration, positioners, automation level, and data-recording requirements.

Key benefits

Controlled low-pressure argon atmosphere for high-purity plasma-sprayed coatings.
Reduced exposure of molten spray particles to reactive gases during deposition.
Closed-loop monitoring and control of critical coating-process parameters.
Integrated chamber-pressure, vacuum-level, atmosphere, gas-flow, powder-feed, cooling, and manipulation monitoring.
GST MCoat™ software for recipes, real-time process monitoring, diagnostics, maintenance, and traceability.
Single- or multi-station workpiece positioning options.
Automated torch and component manipulation for repeatable processing.
F4VB-VPS plasma gun designed for reduced-pressure operation and high thermal loads.
Ability to perform substrate preheating, cleaning/activation, and plasma spraying within the controlled chamber environment.

System configuration

The VPS 3000 is configured as a complete controlled-atmosphere coating system. The exact chamber size, vacuum package, manipulation concept, and process equipment are selected for the application.

Vacuum plasma spray process inside the VPS 3000 coating chamber

Vacuum process chamber

The coating process takes place inside a sealed chamber that is evacuated and then backfilled with argon. Chamber dimensions and internal layout are selected according to the size and geometry of the components and the required automation concept.

VPS 3000 process control center for vacuum plasma spray equipment

Process control center & software

The digital control system provides centralized operation through a high-resolution color touchscreen. Closed-loop control supervises critical variables such as process gas pressure and flow, plasma gun electrical parameters, cooling-water conditions, chamber pressure, vacuum level, chamber atmosphere, powder feed, manipulation status, and safety interlocks.

VPS processes require coordinated supervision of both the plasma spray process and the chamber environment. The VPS 3000 control architecture therefore monitors the coating equipment together with vacuum, atmosphere, cooling, powder feed, manipulation, and safety conditions.

GST MCoat™ provides a common operator environment for process programs, diagnostics, data acquisition, external-module control, user access, maintenance planning, and traceability.

Main software functions

Graphical operator interface with process visualization.
Spray-gun library and process-program management.
Remote diagnostics.
Real-time parameter monitoring and recording.
Control and supervision of external modules.
Multi-level user access.
Maintenance planning.
Resource-consumption monitoring.
Closed-loop monitoring of chamber pressure, vacuum, atmosphere, process gases, gun electrical parameters, cooling, powder feed, manipulation, and safety interlocks.

Applications

Turbine blades for MCrAlY vacuum plasma spray coatings

Aerospace and turbine components

VPS is selected where the coating process benefits from a controlled low-pressure atmosphere and reduced oxidation. Typical applications are aerospace and medical components; the process is also suitable for demanding energy-sector applications.

MCrAlY-type coatings are used for high-temperature aerospace components. Typical parts include turbine blades, turbine components, sealing components, rings, and other parts requiring controlled coating chemistry and oxidation resistance.

Titanium-coated femoral stem for medical implant applications

Dental implant with titanium coating for VPS medical applications

Medical implants

VPS can be used for high-purity titanium coatings on medical implants. Typical examples include artificial hip joints, femoral stems, knee implants, dental implants, and other orthopedic components.

FAQ

What is vacuum plasma spraying?

Vacuum plasma spraying uses the same fundamental plasma-heating principle as APS, but the coating is deposited inside a controlled low-pressure atmosphere. The chamber is evacuated and then backfilled with argon to reduce the influence of reactive gases during spraying.

Why use VPS instead of atmospheric plasma spray?

VPS is selected when the coating benefits from reduced oxidation, high purity, controlled substrate preparation, and a controlled process atmosphere. The required technology should be chosen according to the coating specification and qualification requirements.

Which plasma gun is used with VPS 3000?

The VPS 3000 uses the F4VB-VPS plasma gun, rated at 55 kW and designed for argon operation with water cooling.

Can the VPS 3000 preheat and activate the surface before coating?

Yes. The F4VB-VPS nozzle geometry supports workpiece preheating and surface cleaning/activation in addition to plasma spraying.

What applications are specifically identified for VPS 3000?

Typical applications include aerospace components such as MCrAlY coatings on turbine components and medical applications such as titanium coatings on orthopedic and dental implants.

Is every VPS 3000 identical?

No. Chamber dimensions, positioners, robot/manipulator configuration, powder feeding, process gases, cooling, vacuum requirements, and data-recording functions are configured to the customer’s production task.
