The 9MB plasma spray gun is well-known in the thermal spray industry for its reliability and is one of the most widely used plasma spray guns globally.
Designed and constructed with precision in high-performance hardware, the 9MB plasma gun offers capabilities in the high-kilowatt range while extending the lifespan of its components.
Carefully designed, the gun achieves optimal heat transfer by evenly distributing cooling water within the electrode and nozzle. This results in reduced downtime, increased productivity, lower maintenance costs, and overall operational cost reduction.
The 9MB is capable of depositing high-quality coatings such as metals, metal alloys, carbides, composite materials, mixtures, metal ceramics, grindable materials, and ceramic powders.
The 9MB is available in a machine-mounted type (9MBM) and a handheld type (9MBH). Its modular structure makes major gun components easy to maintain, and both nozzles and electrodes are simple plug-and-play components.
The 9MB operates efficiently, using pure argon or nitrogen as the primary gas, or it can be operated with multiple gas parameters such as argon, nitrogen, hydrogen, and helium.
Common consumable parts for the 9MB plasma spray gun include electrodes and nozzles. Our company provides matching electrodes and various models of nozzles.

Advantages 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.
| Material | Impurity content (%) | Electron work function (eV) |
| Lanthanum tungsten | <0.2 | 2.8-3.2 |
| Cerium tungsten | <0.2 | 2.7-2.8 |
| Thorium tungsten | <0.2 | 2.0-3.9 |
4. 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.
