▎ 摘　　要

NOVELTY - The composite diamond ethylenically artificial joint has a joint head that is provided with a joint socket, which is provided with a metal substrate (1) provided with a superfine diamond graphene layer (2). A basal body is provided with a wear-resisting layer (3). A surface roughness joint socket is provided with a layer-shaped crystal structure. USE - Composite diamond ethylenically artificial joint. ADVANTAGE - The composite diamond ethylenically artificial joint has a joint head that is provided with a joint socket, which is provided with a metal substrate provided with a superfine diamond graphene layer, and hence enhances the hardness, wear resistance and life. DETAILED DESCRIPTION - The drawing shows a schematic view of a method for preparing the composite diamond ethylenically artificial joint. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the composite diamond ethylenically artificial joint.
