Abstract

L'invention concerne la pulvérisation d'un métal fondu. Elle se rapporte à un appareil dans lequel un courant d'air à très haute pression, provenant d'une chambre 31, forme un courant conique 21 qui crée en son centre une aspiration dans une zone 19, si bien que le métal fondu des fils 8a, 8b est aspiré par la dépression créée et est pulvérisé et refroidi rapidement dans le courant d'air à pression élevée. Application à la formation de depôts métalliques par projection de métal fondu.
