The prosthetic joint has at least two members (2, 3) having each a cooperating articulating surface layer (10, 11) on a substrate material. At least one of said articulating surface layers comprises amorphous diamond-like carbon; or TiN on a bonding layer (12, 13) bonded to the substrate material. The prosthetic joint provides a reduction of the number of wear debris and shows enhanced dry run properties.
