DUAL WIRE ARC
The arc spraying process involves the use of two consumable metal wires. When the wires make contact, their opposing electrical charges generate enough heat to melt the tips of the wires, creating a liquid. Compressed air—or occasionally nitrogen—is used to atomize the molten material and spray it onto the substrate to form the coating layer. The method is especially suitable for providing corrosion protection to materials with low melting points.
ADVANTAGES OF DUAL WIRE ARC
- Lower operating costs.
- Higher material output per hour.
- Production of a more coarse coating.
- Flexible, can coat a variety of materials.
ORIGINS AND DEVELOPMENT
One of the many, modern applications of metal spraying, which had its origins rooted in the early 20th century in Zurich, Switzerland. It was there that the first processes were developed for spraying metal and, in tandem, the first equipment created to spray metal in wire form.
Dual wire arc coatings continue to be used for conventional, and un-conventional applications.
