X Ray Tube Stationary Anode

Product Description

 

Product Description

1,A stationary anode in the context of X-ray tubes is an anode that does not rotate, unlike a rotating anode, which is commonly used for higher power X-ray generation. Stationary anodes are typically used in applications like dental radiology and portable X-ray systems, where the power requirements are lower. A common material for stationary anodes is a copper-tungsten composite, which offers a good balance of thermal conductivity and resistance to heat damage. 

 

Here's a more detailed explanation:

Stationary vs. Rotating Anodes:

• Stationary Anode:

  The anode, a target material where electrons bombard to produce X-rays, remains fixed in position.
• Rotating Anode:

  The anode is a rotating disc, typically made of tungsten or a tungsten alloy, that spins at high speeds to distribute the heat generated by electron bombardment over a larger surface area, allowing for higher power X-ray generation. 

   

Applications:

• Stationary Anodes:

  Used in applications where lower power X-ray output is sufficient, such as:

  • Dental radiology
  • Portable X-ray units
  • Some types of fluoroscopy
• Rotating Anodes:

  Used in applications that require higher power X-ray output, such as:

  • General radiography
  • Angiography
  • CT scanners 
     

Materials:

• Stationary Anodes:

  Often made of a composite material like copper-tungsten, combining copper's good thermal conductivity with tungsten's high melting point and ability to emit X-rays when bombarded by electrons. 

   
• Rotating Anodes:

  Typically made of a target material like tungsten or a tungsten alloy, which is bonded to a copper base. 

   

Advantages of Stationary Anodes:

• Simpler design and construction
• More cost-effective for low-power applications
• Suitable for portable or compact X-ray systems 
   

Disadvantages of Stationary Anodes:

• Limited heat dissipation capacity compared to rotating anodes
• Lower X-ray output power compared to rotating anodes
• May experience localized heating and limited surface area for X-ray production 

 

Comparison with Rotating Anode Tubes:

In Essence: Stationary anode X-ray tubes are a cost-effective solution for applications where the demands on power and heat dissipation are relatively low.

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
