Beschreibung
Zusammenfassung:	The invention relates to the nozzle construction for thermal spraying by means of a suspension, in which particles are contained, or a precursor solution, by means of which particles or precursor solution a layer is formed on a substrate, and which suspension or precursor solution is fed into a burner chamber or into a plasma torch, in which heating and acceleration of the particles is achieved, wherein a connection point for feeding the suspension or the precursor solution, a holder, and a nozzle insert are present. The nozzle insert has, with a tubular element arranged in the direction of the burner chamber or perpendicularly in HVOF flame or plasma torch and with an end face arranged opposite the burner chamber, a flange-shaped expanded section, which lies against a seat formed in the holder in the installed state. The contours of the flange-shaped expanded section and of the seat are complementary to each other such that the surfaces of the flange-shaped expanded section and of the seat are in direct contact with each other and an end stop and a seal are formed in this region.
