COMPOSITE BIO-IMPLANT AND PRODUCTION METHOD THEREFOR

摘要

A composite bio-implant obtained by covering a metal substrate particularly with ceramic particles having bio-compatibility, subjecting the substrate to plastic working so as to cause plastic deformation of the metal substrate, and burying the ceramic particles into the surface layer portion. By applying a ceramic material having bio-compatibility to the surface of the substrate, a composite implant providing higher bonding can be obtained.
