Abstract

L'invention concerne un procédé servant à augmenter, au moins localement, la résistance et/ou la limite de charge de pièces usinées (10), selon lequel une première pièce (11) est d'abord produite selon un procédé de fabrication conventionnel. Le procédé selon l'invention présente les étapes suivantes : on pratique d'abord un trou (13) dans la première pièce (11), dans la zone où il faut augmenter la résistance et/ou la limite de charge ; on introduit ensuite dans le trou (13) une deuxième pièce (12) constituée d'un matériau augmentant la résistance et/ou la limite de charge ; on frotte enfin, dans cet état, la deuxième pièce (12) contre la première pièce (11) selon la méthode du soudage par friction jusqu'à ce que soit atteinte la température de soudage inférieure à la température de fusion des deux pièces (11, 12), de façon à obtenir une liaison par soudage par friction entre la première pièce (11) et la deuxième pièce (12) afin de réaliser la pièce voulue (10).
