Product Description Product DescriptionA F4 electrode is a critical component in plasma spray guns, specifically designed for thermal spraying applications. It serves as the anode (or cathode, depending on configuration) in plasma arc generation, facilitating material deposition through high-temperature plasma jets.Key Features:Material Composition:Typically made of tungsten-copper composite (W-Cu) or pure tungsten, optimized for high thermal conductivity and arc stability.Tungsten undergoes densification treatment to refine grain structure, enhancing hardness and resistance to arc erosion.Manufacturing Technology:Uses back-casting (CBT) technology to achieve seamless bonding between tungsten and copper, ensuring uniform heat dissipation and mechanical strength (bonding strength up to 127 MPa).Eliminates weak points from traditional brazing, improving durability.Performance Advantages:Fast arc initiation and stable voltage output, reducing power fluctuations.Compatible with multiple plasma spray systems (e.g., Metco, GTV, FST, AMT AG, Praxair).Extends service life due to superior anti-erosion and heat dissipation properties.Applications:Widely used in ceramic, metal, carbide, and composite coatings.Supports argon, hydrogen, nitrogen, or helium as plasma gases.Technical Specifications (Example):Current Rating: Up to 1000A (Debye1000 series).Modular Design: Allows easy replacement and maintenance.For further details on F4 electrode customization or compatibility with specific spray guns, consult manufacturers' technical documentation.F4 electorde and nozzle models: Product modelProduct nameRelated product modelWLE-F4F4 electrode1072006WLN-F4-5F4 nozzle1088066WLN-F4-6F4 nozzle1072007WLN-F4-7F4 nozzle1088062WLN-F4-8F4 nozzle1088057There are many F4 electrode manufacturers on the market, but many of them can only make similar sizes, but there are many differences in service life and performance. As a professional manufacturer, we not only know how to produce, but also how to improve and understand customer's use, so we can provide more professional online services.If you have any needs, users are welcome to come for consultation. Our company has a group of experienced technical and sales teams who will serve you wholeheartedly. 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<0.22.8-3.2Cerium tungsten<0.22.7-2.8Thorium tungsten<0.22.0-3.94. 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.
