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 (2.1 and/or 2.2) used for forming the coating forms a cathode and/or an anode that are connected to a direct electrical current source and between which an electric arc is formed, wherein wire-shaped or band-shaped material (2.1 and/or 2.2) may be fed by means of a feed device;
- and
- melted and/or evaporated material of the wire-shaped or band-shaped material (2.1 and/or 2.2) flows, by means of a gas jet (3) of a gas or gas mixture, through an inlet into the interior of a chamber (4) 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 respectively highest evaporation temperature and
- the material(s) completely evaporate(s) and exits through at least one opening (5) present on the chamber (4) and impinges on the surface to be coated of the component or tool (6) for forming the respective coating.
