Sintering is a technology for processing parts, which involves hardening metal powder and baking it at a temperature below the melting temperature of the metal to form the “part”. This process is called powder metallurgy. Hardened formed parts are called “sintered metals” or “sintered products”.<\/p>\n

Le processus de fabrication des produits fritt\u00e9s est le suivant :<\/p>\n

    \n
  1. Mati\u00e8res premi\u00e8res : Les principales mati\u00e8res premi\u00e8res pour les produits fritt\u00e9s comprennent le fer, le cuivre, l'aluminium, le titane, le nickel, le tungst\u00e8ne et l'alumine. La plupart des poudres brutes peuvent \u00eatre utilis\u00e9es.\"\"<\/li>\n
  2. M\u00e9lange : En ajoutant du nickel et de l'oxyde d'aluminium au fer, des produits moul\u00e9s aux caract\u00e9ristiques vari\u00e9es peuvent \u00eatre fabriqu\u00e9s. Ces poudres m\u00e9talliques sont soigneusement m\u00e9lang\u00e9es \u00e0 l'aide d'un m\u00e9langeur.\"\"<\/li>\n
  3. Moulage par compression : Remplir la poudre m\u00e9tallique dans le moule pour le moulage par compression. Compresser verticalement sous haute pression pour augmenter la densit\u00e9 et la r\u00e9sistance. Le moulage par frittage est couramment utilis\u00e9 pour les formes complexes, mais il est limit\u00e9 par la structure du moule.\"\"<\/li>\n
  4. Firing and molding: By heating the compressed parts, the sintered products have strong mechanical properties. Sintering means “baking and bonding”, baking in a sintering furnace at a temperature below the metal melting temperature (800 to 1300 \u00b0 C). The sintering furnace is filled with protective gas to prevent oxidation of formed products. The powder particles in sintered products become stronger through melting and bonding.\"\"<\/li>\n
  5. Taille : Am\u00e9liorer la pr\u00e9cision dimensionnelle des produits fritt\u00e9s en appliquant \u00e0 nouveau une pression dans le moule.<\/li>\n
  6. Traitement post-formation : Afin d'am\u00e9liorer encore la pr\u00e9cision et la r\u00e9sistance, un usinage et un traitement thermique peuvent \u00eatre effectu\u00e9s si n\u00e9cessaire. De plus, en raison de l'utilisation de moules de haute pr\u00e9cision pour le frittage, la pr\u00e9cision dimensionnelle est \u00e9lev\u00e9e et il y a moins de traitement apr\u00e8s la formation. Gr\u00e2ce \u00e0 sa capacit\u00e9 \u00e0 produire des pi\u00e8ces de haute pr\u00e9cision \u00e0 grande \u00e9chelle, le frittage est utilis\u00e9 pour fabriquer divers composants m\u00e9caniques tels que des roulements et des engrenages, y compris des composants automobiles.<\/li>\n<\/ol>\n
