Sg100 Plasma Spray Electrodes and Pure Copper Anode

Product Description

 

An SG100 anode is the nozzle of the SG100 plasma spray gun, a water-cooled component typically made from high-purity copper or its alloys that is integral to generating and stabilizing the plasma for thermal spray coating applications. Designed for high-volume production, the SG100 anode's internal geometry, like the Laval nozzle design, and smart cooling channels help maintain stable temperatures for consistent coating quality, long operational runs, and reduced maintenance. 

Purpose of the SG100 Anode

The SG100 anode serves as a critical component in the SG100 plasma spray gun assembly, functioning as the anode to generate and sustain an extremely high-temperature plasma arc (exceeding 12,000°C) in conjunction with the cathode, enabling the melting and acceleration of injected metallic, ceramic, or cermet powders onto substrates to form protective coatings for applications such as wear resistance, corrosion protection, and thermal barriers.

SG-100 plasma spray gun
    The SG100 plasma spray gun produced by Praxair is a very flexible spray gun that can be used in a variety of application scenarios. Its operating power is 80KW. If you have higher requirements for coatings, or require large-volume production, or small-volume testing, the SG100 spray gun can be used very well.
    This spray gun has two modes: internal powder feeding and external powder feeding. Different modes can provide multiple incident angles, obtain better spraying speed, or mix multiple spraying materials.
Different modes, matched with different hardware, can form different working modes. We can provide suitable nozzles (anode) and electrodes (cathode) for different modes.
What material is used for the anode?
As you can see, all copper materials are used on the market, but there are many types of copper materials, and the purity and composition of different copper materials are different. For specific industries that require special treatment of copper materials, we have been supplying copper anodes to different industries and are very clear about customers' material requirements in different industries.
Anode matching:
The product accessories provided by Praxair have high precision, and general processing manufacturers can provide similar shapes. However, there is a very big gap in the actual control of product size.
We have been providing anode and cathode accessories for various plasma spraying service providers, and we can control the size very accurately.

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.
