This intense plasma arc melts injected feedstock materials (metallic, ceramic, or cermet powders) and accelerates them onto substrates to form dense, protective coatings for applications requiring wear resistance, corrosion protection (e.g., anti-corrosion, rust removal), thermal barriers, or electrical insulation. Its design is fundamental to shaping the plasma jet and achieving consistent coating quality.Key performance characteristics of the SG100 nozzle include:Material & Construction: Utilizes a copper-embedded tungsten alloy design. This is achieved through advanced manufacturing techniques like Back Casting (NDB), ensuring a seamless metallurgical bond between the high-conductivity copper body and the wear-resistant tungsten insert. This eliminates interfacial gaps and enhances structural integrity.Superior Thermal Management: The seamless bond provides exceptional thermal conductivity and efficient heat dissipation from the tungsten insert through the copper body to the cooling system. This prevents localized overheating, reduces thermal stress cracking, and enables stable plasma generation during prolonged high-power operation (up to 80 kW).Extended Service Life & Durability: Offers outstanding resistance to arc erosion and wear compared to conventional nozzles. This translates into a significantly longer operational lifespan, often cited as averaging 200-300 hours under typical operating conditions, directly reducing consumable costs and downtime.Unique Powder Injection Flexibility: Designed to support both internal powder injection (optimal for energy transfer and particle velocity, yielding high deposition efficiency and coating quality) and external powder injection, or a combination of both. Multiple injection angles are available, enhancing versatility for different materials and applications.Self-Aligning Design & Ease of Maintenance: Features a self-centering design with fewer parts. This ensures precise concentricity (critical for stable plasma arcs and preventing nozzle wear/powder buildup) and allows for rapid, foolproof assembly and replacement, minimizing maintenance downtime.Process Stability & Compatibility: Contributes to stable plasma arc characteristics and consistent coating deposition. Compatible with various plasma gases (Ar, N2, He, H2) and gas mixtures (e.g., Ar-H2, Ar-He), with helium use noted for further extending component life.Gas Efficiency & CE Compliance: Designed for low gas consumption and meets stringent CE safety requirements.The SG100 nozzle is critically important for several reasons:Core Component for Plasma Generation: It is indispensable for creating the stable, high-energy plasma jet essential for melting and accelerating coating materials effectively.Coating Quality & Consistency: Its stable plasma arc performance and precise powder injection capability (especially internal injection) are paramount for achieving high-quality, uniform, reproducible coatings with strong adhesion, essential for demanding applications in aerospace, medical devices, energy, and heavy industry.Operational Efficiency & Cost Reduction: The extended service life and ease of maintenance significantly lower operational costs by reducing consumable replacement frequency and associated machine downtime, boosting overall productivity.System Reliability & Versatility: Its robust construction and thermal management ensure reliable performance under high-stress conditions, while its compatibility with different injection modes and gases makes the SG100 gun exceptionally versatile for a wide range of coating materials and production requirements (both high-volume and flexible small batches).Process Safety: Reliable performance contributes to the overall safety of the plasma spray operation.SG100 plasma thermal spray nozzle and electrode models Product modelProduct nameRelated product modelWLE-SG100-129SG100 electrode843083129WLE-SG100-720SG100 electrode841083720WLN-SG100-730SG100 nozzle02083-730WLN-SG100-145SG100 nozzle03083-145WLN-SG100-165SG100 nozzle03083-165WLN-SG100-175SG100 nozzle03083-175If you have any needs, users are welcome to come for consultation.

Weilai devotes to research and develop high performance heterogeneous refractory metal composites, including high-performance X-ray tube anode material, plasma spray nozzle as well as the electrodes and the resistance welding electrodes, etc. It is mainly used in medical equipment, plasma spray and automobile electrical equipment industries. Weilai provides the customized solutions for customers, it is a high-tech company integrating research and development, production, sales and service. Adhering to "Keep improving products and creating value for customers", the company focuses on the subdivided fields of refractory metal materials industry, continuously optimizes the technological adaptability of products, develops more supporting products in the industry, and provides users with more reasonable and comprehensive solutions. 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.
