A method of manufacturing the same, as well as artificial joints using the same biocompatibility and low wear and member

摘要

It is to suppress the friction of the sliding parts, and to suppress the generation of wear debris. Moreover, the sliding member, the present invention, their preparation and prosthesis can be in vivo, and to maintain sufficient mechanical properties It is to provide a method. Providing a substrate capable of forming 1, and a biocompatible material layer 4 laminated appropriately. Part of the substrate 1 hydroxyl group, the base material 1, forms a hydroxyl group by a surface treatment to the required location, at least on the surface While providing a surface treatment layer 2 by, biocompatible material layer 4, the biocompatible material also while constructed from a polymer containing a phosphorylcholine group, to form covalent bonds with the hydroxyl group, and a biocompatible material layer 4 and the substrate 1 and are bonded through an adhesive layer 3 made of silica covalently attached.
