摘要： Methods for forming bone implants for the repair of the ends of bones at orthopedic joints, which implants have a Young's modulus close to that of human cortical bone. Substrates of dense isotropic graphite are coated overall with hard, microporous, isotropic pyrocarbon of specific character such that it can be polished to serve as an articular surface and can also securely receive an anchoring first metal layer through PVD. The first layer has a character such that, by thermal spraying a second biocompatible metal layer thereupon, fusion occurs and thereby anchors an outermost layer that is formed with a network of randomly interconnected pores and a surface character of peaks and valleys designed to promote enhanced appositional growth of cortical bone at the interface therewith.
