Tougher demands on thermal barrier and wear coatings have made plasma spraying one of the most widely used processes within the coating industry. Electrodes and nozzles play an important role in the plasma gun assembly, as the electric arc is generated between them.
PLANSEE is a leading producer of tungsten/copper parts. Based on our experience, we offer the complete product range of electrodes and nozzles for all known plasma spray guns. Due to back-casting with copper, a special material joining process at PLANSEE, electrodes and nozzles perform better during operation than e.g. brazed components. Our production program includes electrodes and nozzles for certain gun types available with or without the corresponding O-rings.
PLANSEE strongly supports the development of thorium-free tungsten qualities and offers lanthanated tungsten inserts for electrodes and nozzles.

Furthermore PLANSEE supplies:
- Pre-machined tungsten/copper blanks
- Electrodes and nozzles with lanthanated tungsten inserts
Based upon experience, service lifetime of G and GH type nozzles can be significantly increased by putting a tungsten insert (liner) into the copper part. This also results in a reduction in down-time for hardware changes and helps minimizing process costs.
