Product Description F1 nozzle is a critical component that acts as the anode to shape and accelerate the high-temperature plasma jet. It is designed for reliability and is known for producing high-quality coatings, particularly on internal surfaces Function and characteristicsAnode: The nozzle serves as the anode, with a cathode placed inside the gun to create an electric arc between them.Plasma generation: A working gas (e.g., argon) is passed through this arc, which heats and ionizes it into a plasma jet with temperatures reaching 10,000-20,000K.Focus and acceleration: The F1 nozzle features a converging section that compresses and focuses the plasma flow, increasing its velocity to supersonic speeds (300-600 m/s).Internal surfaces: The F1 gun is particularly well-suited for coating internal diameters of 75mm (3 inches) or larger. It is available in different configurations with angled heads (e.g., F1-90 and F1-45) for hard-to-reach areas.Material: To withstand the extreme heat and erosion, F1 nozzles are often made of materials like copper, with a tungsten lining for extended lifespan. They are also typically water-cooled. The coating processThe F1 nozzle works as part of a system to create coatings in the following sequence:Arc formation: An electric arc forms between the cathode and the F1 nozzle (anode).Plasma jet creation: A gas flows around the arc and is ionized, creating a high-velocity plasma jet.Powder injection: Powdered coating material is injected into this jet and melts.Coating formation: The molten powder is propelled toward the substrate at high speed, forming a durable coating upon impactThe corresponding list of the nozzle electrode model of our company's F1 and the model of FST's productsProduct modelProduct nameRelated product modelWLE-F1-SF1 threaded electrode340001WLE-F1-PF1 pin electrode343001WLN-F1-5F1 nozzle340002WLN-F1-6F1 nozzle343002 If you have any needs, users are welcome to come for consultation.

Our AdvantagesAdvantages of plasma spray nozzles and electrodes produced by our company:1. Our company has been engaged in the production of pure tungsten and tungsten alloy materials for many years, and has an in-depth understanding of the structure and properties of materials. For the tungsten electrode used in plasma spraying electrodes, based on our full understanding of the application, we have made more improvements and treatments to the material structure to meet the material requirements of plasma spraying. By densifying the tungsten electrode, a finer, more uniform grain structure is formed. The modified tungsten alloy has relatively high hardness and density, fast arc starting, excellent resistance to arc burning loss, and long life.2. Our company's plasma spraying electrodes and nozzles use unique back-casting technology to achieve seamless bonding between tungsten and copper. The bonding strength can be as high as 127MPa, while the traditional bonding strength is less than 100MPa. Compared with traditional brazing, joints made by back-casting have higher bonding strength between tungsten and copper, larger contact area, more uniform resistance, and stronger heat dissipation ability, making the nozzle and electrode more stable and more durable as well as long service life.3. We produce tungsten electrodes of different materials (good arc starting performance and ablation resistance). Based on customer usage conditions, we can provide more suitable materials for customers to choose. MaterialImpurity content (%)Electron work function (eV)Lanthanum tungsten<0.2<>2.8-3.2Cerium tungsten<0.2<>2.7-2.8Thorium tungsten<0.2<>2.0-3.94. Based on the research and analysis of plasma spray guns, the electrodes and nozzles produced by our company can perfectly adapt to the original spray guns, and no additional adjustment of spraying parameters is required during replacement. We have a complete product series, and the plasma spray electrodes and nozzles we produce can be widely used in F4, 9M, SG-100 and other spray guns of Metco, GTV, FST, AMT AG, Praxair and other companies.5. We have rich experience in producing various cathodes and anodes, which can be customized and processed according to customer samples or drawings. We can also provide semi-finished products with seamless combination of tungsten and copper.After Sales Service We can ensure our all products which are seamless bonding,no gas foam generating,and assure concentricity,if any defect has been found which are due to our cause,we can replace them for free and send you along with shipment for next time.
