| description | The invention relates to a nozzle plate for a plasma spraying machine for atmospheric plasma spraying and to such a plasma spraying machine. The nozzle plate is made of an electrically conductive material and has a central through-hole through which a receiving geometry for a ceramic ring of a plasma sprayer is formed. A coolant channel through which a liquid coolant can flow is integrated into the nozzle plate, the channel inner wall of which is formed from the material of the nozzle plate. An annular channel portion of the coolant channel annularly surrounds the through-hole in the material of the nozzle plate. According to the invention, the coolant channel has a channel interior in a predetermined maximum cooling demand region of the nozzle plate, which channel interior is designed in such a way that, when the coolant channel flows through the coolant channel with the coolant, bubble formation of the coolant in a channel section of the coolant channel associated with the maximum cooling demand region is p |
