Definitions

  • a method is also described which involves dipping the member into a suspension of the hydride of the member of the core and subsequently heating the core at high temperature.
  • the porous body or the porous layer is formed by small discrete particles of metal welded together and for a proportion of them to the substrate or core. These welded connections only occupy limited space so that between the particles free spaces are left which provide the desired porosity. These particles may be cylindrical or spherical.
  • the contact between the spherical or cy lindrical particles before the welding operation is reduced to a point or to a line. It is thus necessary that the operation of welding should itself give rise to the growth of a contact surface of larger size when filaments or atomized powders are sued.
  • This welding can only be effected by roasting, that is to say, by thermal treatment at elevated temperature, about 1200C in the case of Vitallium, 1100C in the case of titanium. At these temperatures diffusion phenomena in the solid phase give rise to the joining of the elements in contact by the growth of joining surfaces from the contact points. These phenomenon are slow and growth of the contact areas slows up when the connecting or joining surfaces increase.
  • the invention relates also to another type of 'improved implant characterized inthat the external surface of the-porous coveringof an implant carriesfine particles of the same.metal as the implant, of a diameter less than microns and welded to this surface.
  • an implant l is illustrated formed from a core 2 and a porous covering 3 constituted by metallic foils 4 of a light gauge and which are superposed on one another.
  • the bone 5 grows into the pores of this porous covering 3.
  • the implant is subjected to shear forces F and to tension forces F,.
  • the prosthesis After drying the prosthesis is treated in a vacuum of l5 l0 mm at l.lC.
