Arc Spraying
Arc spraying is a thermal spraying process in which two metal wires are electrically welded and atomized onto a substrate.
It is a cost-effective and fast method for applying protective metallic coatings, such as zinc, aluminum, or steel, to larger surfaces.
This technique is ideal for corrosion protection and surface repair of large-scale structures or machine parts.
How Does the Process Work?
- Two metal wires (positive and negative) are brought together.
- When they touch each other, an electric arc is created that melts the metal.
- Compressed air atomizes the molten metal and blows it onto the surface of the component.
Advantages
Fast and economical
No heat input into the workpiece (cold technique)
Good adhesion and coverage
