Atmospheric plasma coating or plasma spraying is one of the thermal coating processes and is ideal for metallic and ceramic materials. For this purpose, a high-speed plasma stream is generated, which reaches temperatures of up to 20,000°C. This enables ceramic as well as metallic materials to be melted and coated. At the outlet of the plasma nozzle, the coating powder is fed in by means of injectors. On the way to the workpiece, the powder particles are accelerated and simultaneously heated so that they hit the surface of the component with high temperature and high kinetic energy. As a result, a corrosion- and/or wear-resistant layer is formed on the surface.
The TPS PSS1000 plasma systems feature the latest automation technology from Siemens TIA Portal or Mitsubishi GX Works.
The simple, user-friendly operator interface and programme sequences evoke a high level of acceptance among the operating personnel right from the first commissioning.
The systems are built according to the latest safety standards. Continuous parameter monitoring and control with high-precision sensors and controllers ensure excellent quality control of your coating process. The Advanced Remote Interface also enables extensive data communication between the plasma system and the robot or other handling systems.
Each TPS plasma system is designed according to customer requirements. For example, with a data acquisition system for all relevant spray and process parameters. The data acquisition (datalogger) system stores the data for an entire process time for a specific component. This protects the components from errors during coating.
Our Core Systems are available in two designs: PSS1000 APS Core System - GMC out and for smaller space PSS1000 APS Core System - GMC in.
In vacuum plasma spraying (VPS), a high-speed plasma jet is generated in the same way as in atmospheric plasma spraying (APS). However, compared to the APS process, the coating process takes place under low-pressure conditions, in a specially designed vacuum chamber. A pump system evacuates the chamber to achieve the desired vacuum level. VPS technology thus enables more precise process control and extended facility utilisation.
• Control of particle heating and particle velocity
• Processing of reactive coating powders (e.g. titanium, iron alloys, silicon).
Areas of application
Almost all coating materials can be processed using vacuum plasma spraying. In addition, the VPS process allows coatings to be applied over a wide pressure range, which is directly reflected in the coating properties (lower coating porosity).
The TPS VSS1000 plasma systems feature the latest automation technology from Siemens TIA Portal or Mitsubishi GX Works. The simple, user-friendly operator interface and programs sequences evoke a high level of acceptance among the operating personnel right from the first commissioning. The systems are built according to the latest safety standards. Continuous parameter monitoring and control with high-precision sensors and controllers ensure excellent quality control of your coatings. The Advanced Remote Interface also enables extensive data communication between the plasma system and the robot or other handling systems. The VPS vacuum plasma spraying system is modular and available in various configurations, from an R&D system to a high-production vacuum coating system with multi-spindle workpiece handling.
In high velocity flame spraying, continuous fuel combustion takes place under high pressure within a water-cooled combustion chamber. The fuels used are "gas fuel" (such as propane, ethylene, propylene, butane, acetylene, hydrogen), "liquid fuel" (e.g. paraffin / isopar) and also combinations of these. The high pressure of the burning fuel-oxygen mixture generated in the combustion chamber and the expansion nozzle create the necessary high velocity of the gas jet.
The spray materials, which are usually in powder form, are fed either axially in the combustion chamber or radially in the area of the nozzle. On their way to the workpiece, the powder particles are accelerated and simultaneously heated so that they hit the surface of the component at high temperature and speed.
The TPS PSS1000 HVOF-GF / -LF* systems feature the latest automation technology from Siemens TIA Portal or Mitsubishi GX Works. The simple, user-friendly operator interface and program sequences elicit a high level of acceptance from the operating personnel right from the first commissioning. The systems are built according to the latest safety standards. Continuous parameter monitoring and control with high-precision sensors and controllers ensure excellent quality control of your coatings. The Advanced Remote interface also enables extensive data communication between the HVOF system and the robot or other handling systems. The HVOF spray system is modular and available in various configurations.
*Depending on the system configuration
GF = gas fuel
LF = liquid fuel
