Abstract

Στο πιστόλι ψεκασμού πλάσματος αέρα και μεταξύ των ηλεκτροδίων (1,4) τοποθετούνται ακροφύσιο εισαγωγής (2) και διηλεκτροδιακό ένθεμα (3). Στο ακροφύσιο (2) υπάρχουν συμπληρωματικοί δίαυλοι αερίου (6) που επικοινωνούν με το δίαυλο τόξου (5). Η εσωτερική διάμετρος του διηλεκτροδιακού ενθέματος (3) είναι τουλάχιστον ίση με τη διάμετρο του κύκλου (8) που περιγράφεται στις οπές εξόδου των συμπληρωματικών διαύλων (6) και η σχέση της διαμέτρου του κύκλου αυτού (8) προς το μήκος του ενθέματος (3) είναι μέσα στην κλίμακα από 0,6 έως 1,7. Όταν το σχηματίζον πλάσμα αέριο (9) προσάγεται εφαπτομενικώς, πίσω από την άνοδο (4) σχηματίζεται μία μη ψυχθείσα αξονική ροή πλάσματος (15) με ομοιόμορφα διαγράμματα (14) θερμοκρασίας και ταχύτητας. ωAn inlet nozzle (2) and a dielectric insert (3) are placed in the air plasma spray gun and between the electrodes (1,4). In the nozzle (2) there are additional gas channels (6) that communicate with the arc channel (5). The internal diameter of the dielectric insert (3) is at least equal to the diameter of the circle (8) described in the exit holes of the complementary channels (6) and the relation of the diameter of this circle (8) to the length of the insert (3) is within the range of 0.6 to 1.7. When the plasma forming gas (9) is supplied tangentially, behind the anode (4) an uncooled axial plasma flow (15) with uniform profiles (14) of temperature and velocity is formed. oh
