Abstract
The plasma gun head for plasma spraying apparatuses essentially comprises a cathode body mender, an anode body member and an insulating member inserted there between and electrically insulating these two members from each other. Inserted into the cathode body member is a cathode assembly, and into the anode body member an anode nozzle, both extending transverse to the longitudinal axis of the plasma gun head. The anode body member and the cathode body member both are provided with cooling channel sections which are connected in series as seen in the direction of flow of the cooling medium. The anode nozzle is rigidly integrated into the anode body member; thus, it is not necessary to provide sealing elements in this thermally highly stressed region. The sealing elements required for sealing the cooling channel sections are located remote from the anode nozzle and the cathode assembly, respectively, in a region, which is thermally not stressed.
