How long do plasma spray nozzles and electrodes last?

How often should the electrodes on the plasma spray gun be replaced, if not, what will be the impact?

The nozzle and electrode of the plasma spray gun are wear parts and need to be replaced after a period of use. The specific time for replacement is related to the spraying parameters used. If spraying with parameters with low power, the life of nozzle and electrode will be longer; if spraying ceramic coating with high power, nozzle and electrode will wear out faster.



In addition, it is also related to the characteristics of the nozzle and the electrode itself. The service life of the nozzle and the electrode with cerium tungsten is longer than that of copper alone. In addition, the machining accuracy of the nozzle and the electrode, whether the installation is coaxial, etc. will also affect the life of the nozzle and electrode.
