Abstract
Official abstract text for this publication.
A method and a device for generating a plasma jet under atmospheric pressure for the surface treatment of workpieces has a supply line for the plasma-capable medium, and an apparatus for electrically exciting the plasma-capable medium by an electric arc periodically ignited between a cathode and an anode constructed as a nozzle. To achieve a highly effective plasma jet even at relatively low temperatures of the plasma jet, a heating apparatus for preheating the plasma-capable medium is arranged upstream of the apparatus for electrically exciting the plasma-capable medium.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for generating a plasma jet under atmospheric pressure for the surface treatment of workpieces, wherein the plasma jet is generated by electrically exciting a plasma-capable medium by means of an electric arc periodically ignited between a cathode and an anode constructed as a nozzle, and the plasma jet is directed through the nozzle in the direction of the surface to be treated, wherein the plasma-capable medium is preheated in a heating apparatus b…
