Cleaning by electrical discharges

Cleaning by electrical discharges

Electrical arc discharges are equally suitable for lacalized and large area SURFACE REMOVAL OPERATIONS: They can be used at atmospheric pressure as well as in vaccum.

Localized cleaning at atmospheric pressure

Surfaces can be locally ablated with a pulsed high voltage discharge under atmospheric pressure.


Large-area cleaning in vacuum

The DC-vacuum arc discharge - known from the coating technology - is an effective tool for large-area removal of surfaces. Metallic surfaces can be cleaned with high processing speed, in vacuum.
