Abstract
A femoral component as herein before described for an artificial hip joint made out of an alloy containing titanium, wherein at least a major load bearing portion of which has been subjected to bombardment by a beam of nitrogen or other light ions having energies in the range of 10 Kev to 200 Kev until a surface fluence of between 1 and 8×1017 ions/cm2 has been implanted. An apparatus for processing such components is described also.
Claims16
A method of producing a femoral component of an artificial hip joint having a spherical head portion attached to an elongated shank, the head portion being made at least primarily of titanium, the method comprising bombarding a surface region of the head portion with light ions having energies in the range 10 to 200 keV until a surface concentration of between 1 and 8×1017 ions/cm2 have been implanted.
