Arc spraying is a highly efficient method for the production of metallic coatings.
The sprayed material is fed in the form of two wires between which an electric arc is ignited. The process temperature reaches up to 4.000 degree Celsius.
The tips of the wires are melted and the molten material is then propelled onto the prepared workpiece surface by means of an atomising gas.
Typical coating thicknesses range from a few tenths of a millimetre to several millimetres.
Composite coatings can also be produced using cored wires with carbide or ceramic cores.
Fields of application:
- Corrosion protection
- Wear protection
- Repair applications
