Abstract

Un plasmatron comprend deux ajutages (2, 3) montés coaxialement, dotés, à l'intérieur de la zone proche de l'axe, de surfaces coniques opposées, séparées par une distance h déterminée par la relation h - d = (0,04...0,22) mm, dans laquelle d représente la dimension maximum des particules en poudre. Un passage annulaire entre lesdites surfaces coniques des ajutages (2, 3) constitue un canal (5) permettant l'acheminement de la poudre jusqu'au jet de plasma. L'invention assure l'alimentation en poudre dans la zone centrale du jet de plasma, du fait du mouvement de ses particules dans le canal (5) à des vitesses approximativement égales.
