Abstract
The invention relates to a device for thermally coating a surface, which has at least one housing (6), a cathode (9), a primary gas distributor (11), a secondary gas distributor (12), electrically and thermally acting insulation elements (13, 14, 16), and an anode, which is designed as a consumable wire and is guided into a nozzle (19, 21) by means of a wire guide (18), wherein the nozzle (19, 21) is mounted in a centered manner and has openings (23) arranged radially in one plane on one of its sides (22).
Claims18
A plasma nozzle comprising
- a housing including:
- a cathode including a tungsten-alloyed core and a copper jacket including a sleeve portion accommodating the core and a flange including a key surface, the sleeve portion including an external thread screwing into a corresponding internal thread of the housing;
- a primary distributor of gas;
- a secondary distributor of gas;
- and
- a consumable wire anode;
- and
- a wire guide guiding the consumable wire anode through the housing.
A plasma nozzle comprising
- a housing including:
- a cathode;
- a primary distributor of gas;
- a secondary distributor of gas having convergently and/or concentrically arranged apertures having different diameters and including an assembly aid;
- and
- a consumable wire anode;
- and
- a wire guide guiding the consumable wire anode through the housing.
A plasma nozzle comprising
- a housing including:
- a cathode;
- a primary distributor of gas;
- a secondary distributor of gas;
- and
- a consumable wire anode;
- and
- a wire guide guiding the consumable wire anode through the housing, the wire guide including a wire guide support of three contact points on its inner circumference and free spaces adjacent pairs of contact points, the three contact points configured to guide the wire through the housing.
