Diamond-ene artificial joint and production method thereof

The invention belongs to the technical field of artificial joints and particularly discloses a diamond-ene artificial joint. The diamond-ene artificial joint comprises an articular head and an articular fossa which are matched with each other. The articular head comprises a metal matrix, and a superfine diamond-ene layer formed by nano diamond-ene is arranged outside the metal matrix. The articular fossa is made of nano diamond-ene and polyethylene, and the volume ratio of the nano diamond-ene to the polyethylene is 2:3 or 1:1. The surface roughness of the articular fossa is smaller than 0.1 micrometer. The diamond-ene artificial joint is high in hardness, good in wear resistance and long in service life.
