| Abstract: | A novel carbon cup has been made of isotropic graphite substrate with high density and high strength ; the surface of the substrate is coated by low temperature pyrolytic isotropic carbon (LTIC). The cup possesses smooth surface, rough inside with mini-holes, excellent mechanical strength, stable chemical property and light weight. It is pressure-resistant, wear-resistant and corrosion-resistant and has ideal biocompatibility, an elastic modulus near to human bone, an osteogenic activity and good surface lubrication. It can be generalized as an excellent material for surface replacement and we have obtained the patent (Patent No. Z L 93 2 35674. 5). |
