These two products are also consumable parts and are one of the most important consumables in plasma thermal spraying. Our company is a manufacturer specializing in the production of plasma spray electrodes and nozzles (also known as plasma cathodes and anodes, tungsten copper cathodes, and tungsten copper anodes). 1)For F4 Plasma Spray Gun Advantages:High Power (50-100 kW): Handles refractory materials (e.g., WC-Co, YSZ) efficiently.XL Nozzle Design: Wider spray pattern (~150 mm) with uniform thickness.Modularity: Quick-change anode/cathode reduces maintenance time.Low Oxidation: Optimized gas mix (Ar/He/H) ensures clean coatings.2)Performance:Particle Velocity: 450 m/s; Temperature: 16,000°C.Coating Quality: Porosity <2%, adhesion >80 MPa.Versatility: Compatible with powders, wires, and suspensions.3)Applications:Aerospace: Thermal barrier coatings (TBCs) for turbine blades.Automotive: Wear-resistant layers on piston rings.Biomedical: Hydroxyapatite coatings for implants.4)Key Accessories:XL Anode/Cathode: Hafnium-doped for extended durability.Hybrid Gas Console: Controls reactive/non-reactive gas ratios.Dual Hopper Feeder: Supports high-throughput (100 g/min).Robotic Mount: Enables automated, precision spraying.5)Here are the operational steps for the F4MB-XL Plasma Spray Gun (concise English version): 1. Pre-Operation Setup:Inspect gun components (anode, cathode, gas lines) for wear/damage.Connect gas supply (Ar/He/H mixture) and cooling water (12 L/min flow).Load feedstock (powder/wire) into the feeder and calibrate feed rate.2. System Activation:Power on the control unit (50-100 kW range).Initiate gas flow (adjust ratios via console) and ignite plasma arc.Stabilize temperature (~16,000°C) and particle velocity (~450 m/s).3. Spraying Process:Position gun 100-150 mm from the substrate.Trigger robotic arm (or manual operation) for uniform passes.Monitor coating thickness in real-time (target porosity <2%).4. Shutdown & Maintenance:Gradually reduce power and gas flow.Purge the system with inert gas to prevent oxidation.Clean nozzle and electrodes; log operational hours.Safety Note: Always wear heat-resistant PPE and ensure proper ventilation.6)High performance F4 plasma nozzle and electrodeIn the plasma spraying process, metal or ceramic powder is melted in a plasma arc and then sprayed at high speed onto the workpiece to be coated. In this way, water-impermeable, highly adhesive coatings can be deposited on tools and various equipment components. When used in spray guns, our electrodes must be able to withstand transient plasma temperatures in excess of 12,000°C. This kind of instantaneous high temperature and pressure is not a problem for our F4 electrode. Our company uses back-casting production technology to form a seamless connection between tungsten and copper, which is extremely strong. Therefore, our electrodes can provide stable working conditions for a long time and extend their service life.Different from the brazing method, brazing uses solder as an intermediate medium to fuse the two alloys, but it is difficult to achieve 100% connection. Therefore, the product produced in this way is first of all not strong enough and is not suitable for the extreme conditions faced in the gun body. High pressure and high temperature can easily cause uneven heat conduction and cracks.The corresponding list of the nozzle electrode model of our company's F4 and the model of other brand productsProduct 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.

Weilai makes constant efforts to "become an excellent company in the field of new materials".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.
