Functions and Properties of the Nozzle and Electrode Of SG100

1. Overview

The SG100 plasma spray system is widely used in thermal spraying applications to deposit coatings (e.g., ceramics, metals, or composites) onto surfaces for wear resistance, thermal insulation, or corrosion protection. The nozzle and electrode are critical components that directly influence plasma generation, stability, and coating quality.

Pure Copper Nozzle

• Thermal Conductivity: Pure copper has excellent thermal conductivity, which helps in quickly dissipating heat and maintaining thermal balance inside the nozzle, reducing thermal stress.
• Corrosion Resistance: Copper is highly resistant to corrosion by most spray materials, especially when handling non-oxidizing or weakly oxidizing materials.
• Cost-Effectiveness: Compared to composite materials containing precious metals, pure copper nozzles are more economical due to their lower manufacturing costs.
• Ease of Machining: Copper has good machinability and can be easily shaped into complex geometries to meet specific spraying needs.
• Temperature Limitations: Although copper has a relatively high melting point, it may soften or deform under extremely high temperatures, limiting its use in some high-temperature spraying applications.

Tungsten-Copper Composite Nozzle

• High-Temperature Performance: Tungsten has an extremely high melting point, and when embedded in copper, it significantly improves the nozzle's overall high-temperature resistance, allowing it to operate stably in extreme heat environments.
• Wear Resistance: Tungsten's high hardness enhances the nozzle's ability to withstand wear from high-speed particle impacts, extending its lifespan.
• Thermal Expansion Coefficient Matching: Through careful design, the thermal expansion coefficients of tungsten and copper are well-matched, reducing thermal stress cracks caused by temperature changes.
• Wide Application Range: Ideal for high-temperature and high-wear spraying operations, especially in applications requiring long-term continuous operation or dealing with refractory materials.
• Higher Cost: Due to the inclusion of tungsten, a rare metal, the production cost of tungsten-copper composite nozzles is higher.

Therefore, pure copper nozzles are better suited for cost-sensitive applications with moderate temperatures. Tungsten-copper composite nozzles are more appropriate for demanding applications with high temperatures and wear, though they have a higher initial cost, they provide greater value over time due to their superior durability and stability.

Performance Advantages of SG-100 Plasma Thermal Spraying Nozzle

• High-Temperature Resistance: The SG-100 nozzle can operate stably at instantaneous plasma temperatures exceeding 12,000°C, ensuring continuous spraying and uniform coating.
• Long Lifespan: The combination of excellent materials and precise structural design gives the SG-100 nozzle exceptional longevity, reducing production costs and minimizing the risk of interruptions.
• High Precision: The SG-100 nozzle can be directly interchanged with original manufacturer spray nozzles without the need for additional size adjustments, making it extremely convenient for customer use and maintenance.
• Customization Services: We offer comprehensive customization services, designing and manufacturing products based on customer needs and specific application scenarios to ensure that products meet various complex requirements.

Applications of SG-100 Plasma Thermal Spraying Nozzle

The SG-100 plasma thermal spraying nozzle has a wide range of applications across various industries, including aerospace, automotive manufacturing, medical fields, and the printing industry, among others. In these industries, it plays a key role in improving product quality, extending lifespan, and reducing costs.

In summary, the SG-100 plasma thermal spraying nozzle, with its outstanding performance and wide application range, has become an indispensable part of modern spraying technology. Choosing high-quality, professionally manufactured SG-100 nozzles will undoubtedly provide reliable support for your spraying process.
