Product Description

Delta Fan-Shaped Three-Anode Plasma Torch Overview

The Delta plasma torch with a fan-shaped three-anode design is a specialized component used in plasma thermal spray coating systems. These anodes (nozzles) are critical consumables that shape and stabilize the plasma jet, ensuring efficient material deposition for coatings in industries like aerospace, automotive, and energy.

Key Features & Design

1. Three-Anode Configuration

   • Unlike standard single-anode torches, the three-anode system improves plasma arc stability and heat distribution, enabling wider spray patterns and higher deposition rates 16.

   • The fan-shaped design helps disperse the plasma jet uniformly, reducing localized overheating and improving coating consistency.

2. Material & Manufacturing

   • Made from high-conductivity copper alloys (e.g., CuCrZr) with tungsten or lanthanated tungsten inserts for erosion resistance 16.

   • Utilizes back-casting technology for seamless bonding between tungsten and copper, enhancing durability and heat dissipation 16.

3. Cooling Mechanism

   • Typically employs natural or forced cooling to manage extreme temperatures (up to 20,000 K in plasma jets).

   • Advanced designs may integrate water-cooling channels to prolong nozzle lifespan 16.

4. Compatibility

   • Designed for Metco, GTV, FST, and Praxair plasma spray guns (e.g., F4, 9MB, SG-100 models) 16.

   • Customizable for specific industrial needs (e.g., HVOF, LPPS coatings).

Applications

• Thermal barrier coatings (TBCs) for turbine blades.

• Wear-resistant coatings for industrial machinery.

• Corrosion protection in marine and chemical environments.

Advantages Over Standard Nozzles

 Extended service life due to erosion-resistant materials.
 Stable arc performance with reduced electrode wear.
 Adaptability for high-power plasma spraying.

Our Advantages

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.

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.
