Method for improving wear resistance of artificial joint material

The invention belongs to the technical field of artificial joint friction and wear, and discloses a method for improving wear resistance of an artificial joint material, an artificial joint comprises a first artificial joint component and a second artificial joint component, and friction surfaces of the first artificial joint component and the second artificial joint component are matched with each other; the first artificial joint component and the second artificial joint component are respectively made of carbon fiber reinforced polyether-ether-ketone and silicon nitride; dipalmitoyl phosphatidylcholine is adopted as a lubricating medium between the first artificial joint component and the second artificial joint component; the friction surface of the first artificial joint component or the second artificial joint component adopting the carbon fiber reinforced polyether-ether-ketone is provided with a surface texture, the surface texture is round pits uniformly distributed on the friction surface, and the r
