Abstract
The prosthetic joint has at least two members having each a cooperating articulating surface layer on a substrate material. At least one of said articulating surface layers comprises amorphous diamond-like carbon; or Titanium Nitrate (TiN) on a bonding layer bonded to the substrate material. The prosthetic joint provides a reduction of the number of wear debris and shows enhanced dry run properties.
