Product Description Product DescriptionA F4 nozzle is a crucial consumable component specifically designed for the F4 plasma spray gun, playing a vital role in thermal spraying operations.Purpose:It functions as the anode within the plasma torch assembly, collaborating with the electrode to generate and sustain an extremely high-temperature plasma arc (exceeding 12,000°C), which melts injected powders such as metals, alloys, ceramics, or carbides and propels them onto substrates to form protective coatings for applications like wear resistance, corrosion protection, and thermal barriers.Performance:Material and Structure: Constructed using a copper-embedded tungsten alloy design, achieved through an advanced Back Casting (NDB) process that ensures a seamless metallurgical bond between the copper body and tungsten insert, eliminating gaps and enhancing overall integrity.Thermal Management: Features exceptional thermal conductivity and heat dissipation capabilities, preventing overheating and reducing thermal stress for stable plasma generation during prolonged operations.Durability and Stability: Offers high resistance to arc erosion and wear, resulting in an extended service life and consistent plasma arc performance, which minimizes process deviations and supports reliable high-volume spraying.Environmental Compatibility: Often utilizes thorium-free tungsten alloys for eco-friendliness, while maintaining compatibility with various plasma gases like argon, hydrogen, helium, and nitrogen.Importance:It is essential for achieving stable and efficient plasma spraying, directly influencing coating quality, uniformity, and adhesion, which are critical for demanding industrial applications in aerospace and heavy machinery.The robust design reduces maintenance frequency and operational downtime, significantly lowering costs and improving productivity in high-power spraying environments.By mitigating risks of nozzle failure and ensuring process safety, it enhances the overall reliability and longevity of the F4 plasma spray system, supporting high-performance outcomesProduct NamePlasma Spray Nozzle(anode)MaterialWLa20-Cu, WLa10-Cu,99.95%SizeNozzle 5mm, Nozzle 6mm,Nozzle 7mm, Nozzle 8mmProduce MethodBondingApplication/IndustrialElectrode/nozzle for F4 spray gun, Metco F4 Spray gun; Areospace, Medical Industry, etc.TypeF4, SG100, F1,F210,9MB/7MB/3MB,Sinplex Pro,Triplex Pro,JP5000,SG200,Axail 3,TPS The F4-VB nozzle is a specialized component in plasma spray guns, designed for high-performance thermal spraying applications. Here's a detailed description based on technical references:1. Design and FunctionThe F4-VB nozzle is an anode (positively charged electrode) in plasma spray systems, typically made from copper-tungsten alloys to withstand extreme temperatures and arc erosion12. It works in conjunction with the cathode (negative electrode) to generate a stable plasma arc, which ionizes gas (e.g., argon, nitrogen) into a high-temperature plasma jet for material deposition.2. Key FeaturesMaterial: Copper-tungsten construction ensures durability and efficient heat dissipation.Compatibility: Specifically designed for Metco F4-VB plasma spray guns, often used in low-pressure plasma spraying (LPPS-TF) and plasma-sprayed physical vapor deposition (PS-PVD) processes.Performance: Optimized for high-power applications (50-100 kW) and low-pressure environments (~200 Pa), enabling precise coating deposition.3. ApplicationsThermal Barrier Coatings (TBCs): Used in aerospace for turbine blade protection.Wear-Resistant Coatings: Applied in industrial machinery to enhance surface durability.For further technical details, consult manufacturer specifications or system documentation F4 electrode 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.

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.
