Abstract

A device for forming coatings on surfaces of a component, band-shaped material, or tool, in which at least one wire-shaped or band-shaped material is used for forming the coating and that is/are connected to a direct electrical current source, wherein an electric arc is formed between wire-shaped materials or between one wire-shaped or band-shaped material and one anode or cathode, wherein wire-shaped or band-shaped material may be fed by means of a feed device; and melted and/or evaporated material of the wire-shaped or band-shaped material flows, by means of a gas jet of a gas or gas mixture, through an inlet into the interior of a chamber that can be heated to a temperature that is at least equal to the evaporation temperature of the at least one material used for the coating or of the material with the highest evaporation temperature, and the material(s) completely evaporates and exits through at least one opening present on the chamber and impinges on the surface to be coated of the component or tool for forming the coating.
