This type of thermal spraying uses wire material as a feed stock. An electric arc is used to provide the heat source by utilizing two current carrying wires. As the wires are fed towards each other the electric current short circuits between the wires creating a temperature of around 4,000°C. This temperature causes the tips of the wire to melt and once molten, compressed air or inert gas is used to atomize and accelerate the feed metal towards the substrate.

One of the advantages of this system is that two different wires can be used simultaneously to produce a pseudo alloy. Cored wires are also available producing coatings with unique properties.

The process is often used when applying to large areas such as corrosion resistance on large components or for the building up of worn components.

Coating Features:

• Whether you need a smooth, rough, thin or thick cover, arc sprayed coatings can provide the results you need for your project. Arc spraying is simple to use and can provide highly reliable and controllable surface effect. Some of the benefits of using arc spraying include:
  Resistant to various corrosive environments
  Electroactive and sacrificial coatings
  Wear, corrosion and cavitation resistance
  High temperature, oxidation resistance
  Prevention of biological pollutants
  Size recovery
  Controlled surface profile or textured surface
  Clamping and non slip surfaces
