A method is provided for depositing a hard wear resistant surface onto a
porous or non-porous base material of a medical implant. The wear
resistant surface of the medical implant device may be formed by a Laser
Based Metal Deposition (LBMD) method such as Laser Engineered Net Shaping
(LENS). The wear resistant surface may include a blend of multiple
different biocompatible materials. Further, functionally graded layers of
biocompatible materials may be used to form the wear resistant surface.
Usage of a porous material for the base may promote bone ingrowth to
allow the implant to fuse strongly with the bone of a host patient. The
hard wear resistant surface provides device longevity, particularly when
applied to bearing surfaces such as artificial joint bearing surfaces or
a dental implant bearing surfaces. An antimicrobial material such as
silver may be deposited in combination with a metal to form an
antimicrobial surface deposit.
