Introduction de la technologie de l'additif par pulv\u00e9risation \u00e0 froid<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tLes poudres m\u00e9talliques pulv\u00e9ris\u00e9es \u00e0 froid peuvent \u00eatre utilis\u00e9es non seulement comme rev\u00eatement, mais aussi comme composant de fabrication additive. Compar\u00e9e aux m\u00e9thodes de fabrication additive par laser ou faisceau d'\u00e9lectrons, la technologie de fabrication additive par pulv\u00e9risation \u00e0 froid a un temps de production plus court, une grande flexibilit\u00e9 de taille et n'est pas affect\u00e9e par la forte r\u00e9flectivit\u00e9 du cuivre, de l'aluminium et d'autres m\u00e9taux sur le laser. Notre poudre m\u00e9tallique atomis\u00e9e au gaz, sp\u00e9cialement con\u00e7ue pour la projection \u00e0 froid, est disponible dans une large gamme d'alliages, y compris le cuivre pur, les alliages CuAg, CuAgZr, CuCrZr, CuZn, CuCrNb et l'aluminium pur, A357, Al2204, Al6061, Al7050, Al5052, A380, Al7075, Al5056, AlSi10Mg.\n\nPendant la pulv\u00e9risation \u00e0 froid, les poudres solides PSD 0-50um sont acc\u00e9l\u00e9r\u00e9es dans une chambre de pulv\u00e9risation \u00e0 froid.\u00a0supersonique<\/a>\u00a0\u00e0 des vitesses allant jusqu'\u00e0 environ 1200\u00a0m\/s<\/a>. Lors de l'impact avec le substrat, les particules subissent\u00a0d\u00e9formation plastique<\/a>\u00a0et adh\u00e8rent \u00e0 la surface.\u00a0Pulv\u00e9risation thermique<\/a>\u00a0techniques, par exemple,\u00a0pulv\u00e9risation de plasma<\/a>pulv\u00e9risation \u00e0 l'arc,\u00a0pulv\u00e9risation \u00e0 la flamme<\/a>ou du carburant oxyg\u00e9n\u00e9 \u00e0 haute vitesse (HVOF<\/a>), les poudres ne sont pas fondues pendant le processus de pulv\u00e9risation.\n\nPlusieurs facteurs peuvent affecter la qualit\u00e9 des rev\u00eatements projet\u00e9s \u00e0 froid et l'efficacit\u00e9 du d\u00e9p\u00f4t. Les principaux facteurs influents sont les suivants\n
    \n \t
  • Type de gaz, par exemple air, azote, h\u00e9lium<\/li>\n \t
  • Pression du gaz<\/li>\n \t
  • Temp\u00e9rature du gaz<\/li>\n \t
  • Taille des particules<\/li>\n \t
  • Propri\u00e9t\u00e9s des mat\u00e9riaux de base, par exemple densit\u00e9, r\u00e9sistance, temp\u00e9rature de fusion<\/li>\n \t
  • Type de buse<\/li>\n \t
  • Substrat<\/li>\n \t
  • Cin\u00e9tique de d\u00e9p\u00f4t (vitesse transversale du pistolet, vitesse de balayage, nombre de passes...)<\/li>\n \t
  • Distance d'\u00e9loignement, distance entre la buse de pulv\u00e9risation \u00e0 froid et le substrat.<\/li>\n<\/ul>\n \n\nNos poudres atomis\u00e9es \u00e0 l'eau avec des poudres tr\u00e8s fines pr\u00e9sentent de nombreux avantages pour la fabrication additive par pulv\u00e9risation \u00e0 froid et sont \u00e9galement extr\u00eamement \u00e9conomiques pour les processus de d\u00e9p\u00f4t de m\u00e9tal par pulv\u00e9risation \u00e0 froid. Cela est d\u00fb aux co\u00fbts de fabrication beaucoup plus faibles de l'atomisation \u00e0 l'eau par rapport \u00e0 la VIGA, en particulier pour l'impression 3D par pulv\u00e9risation \u00e0 froid \u00e0 base de fer, comme 316L, Invar 36, 300M, M2, 304L.\n\n \nCertaines poudres d'alliage de titane et d'alliage de nickel plus co\u00fbteuses sont \u00e9galement utilis\u00e9es dans la projection \u00e0 froid, comme leCP Ti, Ti6Al4V, et Inconel 718, Inconel 625, NiCr8020, nickel pur. La projection \u00e0 froid de tantale et de niobium, encore plus co\u00fbteuse, est \u00e9tudi\u00e9e en raison de sa temp\u00e9rature plus basse que celle de la projection thermique.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
