Qu\u2019est-ce que le brasage sous vide ?<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Le brasage sous vide est un proc\u00e9d\u00e9 d\u2019assemblage de haute qualit\u00e9 et reproductible, dans lequel les joints sont r\u00e9alis\u00e9s dans un four sous vide \u00e0 des temp\u00e9ratures comprises entre <\/span>800\u00b0C et 1200\u00b0C<\/strong>. Comme le processus se d\u00e9roule sous vide, l\u2019oxyg\u00e8ne et les impuret\u00e9s sont absents, ce qui signifie qu\u2019il n\u2019y a <\/span>pas d\u2019oxydation<\/strong> et <\/span>pas besoin de flux<\/strong>.<\/span><\/p>

Gr\u00e2ce \u00e0 l\u2019action capillaire (dans les interstices de brasage tr\u00e8s pr\u00e9cis), le mat\u00e9riau d\u2019apport (souvent \u00e0 base d\u2019argent, de cuivre, de nickel et\/ou d\u2019or) s\u2019\u00e9coule entre les pi\u00e8ces, ce qui donne une liaison extr\u00eamement solide<\/strong> et propre (aspect m\u00e9tallique brillant). Ce proc\u00e9d\u00e9 convient \u00e0 tous les m\u00e9taux tels que l\u2019acier inoxydable et le titane, les alliages de cuivre et de nickel ayant un point de fusion sup\u00e9rieur \u00e0 environ 800\u00b0C. Divers mat\u00e9riaux non m\u00e9talliques comme le graphite, le carbure, le diamant et la c\u00e9ramique peuvent \u00e9galement \u00eatre bras\u00e9s sous vide.<\/p>

Le processus<\/h6>
  • Pr\u00e9paration :<\/strong> Nettoyage minutieux des pi\u00e8ces et application du mat\u00e9riau d\u2019apport (feuille, p\u00e2te ou fil).<\/li>
  • Chauffage :<\/strong> Les pi\u00e8ces sont chauff\u00e9es dans un four sous vide avec un profil de temp\u00e9rature contr\u00f4l\u00e9, au-dessus de la temp\u00e9rature de fusion du brasage, puis refroidies de fa\u00e7on contr\u00f4l\u00e9e (avec de l\u2019azote\/argon). Le brasage sous hydrog\u00e8ne est \u00e9galement possible.<\/li>
  • Assemblage :<\/strong> Le brasage liquide mouille les surfaces.<\/li>
  • Refroidissement :<\/strong> Un refroidissement contr\u00f4l\u00e9 assure une microstructure uniforme et une d\u00e9formation minimale.<\/li>
  • Contr\u00f4le :<\/strong> Inspection visuelle et tests d\u2019\u00e9tanch\u00e9it\u00e9 et de r\u00e9sistance.<\/li><\/ul>
    Principaux avantages<\/h6>
    • Haute qualit\u00e9 :<\/strong> Liaisons tr\u00e8s solides (souvent \u00e9quivalentes \u00e0 la r\u00e9sistance du mat\u00e9riau de base), \u00e9tanches et r\u00e9sistantes \u00e0 la corrosion\/chaleur. De plus, des joints tr\u00e8s propres, hygi\u00e9niques et sans interstices (aucun flux n\u00e9cessaire). Important pour l\u2019industrie alimentaire ou m\u00e9dicale.<\/li>
    • Grande libert\u00e9 de conception :<\/strong> \u00c9paisseur variable possible, grandes surfaces peuvent \u00eatre assembl\u00e9es.<\/li>
    • Plusieurs assemblages :<\/strong> Plusieurs liaisons peuvent \u00eatre r\u00e9alis\u00e9es en une seule \u00e9tape. La fabrication de produits complexes est possible.<\/li>
    • Polyvalent :<\/strong> Possibilit\u00e9 d\u2019assembler des mat\u00e9riaux dissemblables, comme la c\u00e9ramique avec l\u2019acier.<\/li>
    • Efficace :<\/strong> Brasage et trempe (par exemple, des matrices) peuvent souvent \u00eatre combin\u00e9s en une seule \u00e9tape.<\/li>
    • Stabilit\u00e9 dimensionnelle :<\/strong> D\u00e9formation minimale, id\u00e9al pour les produits complexes et pr\u00e9cis.<\/li><\/ul>
      Domaines d\u2019application<\/h6>

      Gr\u00e2ce \u00e0 sa fiabilit\u00e9 \u00e9lev\u00e9e et \u00e0 la possibilit\u00e9 de fabriquer des composants de pr\u00e9cision, le brasage sous vide est largement utilis\u00e9 dans :<\/p>

      • A\u00e9ronautique et spatial :<\/strong> Pour des composants r\u00e9sistants \u00e0 la temp\u00e9rature.<\/li>
      • Industrie m\u00e9dicale :<\/strong> Pour des liaisons hygi\u00e9niques et sans interstices.<\/li>
      • Construction m\u00e9canique :<\/strong> Pour l\u2019assemblage d\u2019acier inoxydable, de carbure, de diamant et d\u2019acier \u00e0 outils.<\/li>
      • Automobile :<\/strong> Pour les syst\u00e8mes hydrauliques et les \u00e9changeurs de chaleur.<\/li>
      • Technologie \u00e9nerg\u00e9tique :<\/strong> Piles \u00e0 combustible et \u00e9changeurs de chaleur.<\/li><\/ul><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
