  • Composite biological implant of a ceramic material in a metal substrate
    Patent number: 5711763
    Abstract: A composite biotic implant of the invention is prepared by coating a metal substrate with ceramic particles preferably having bio-compatibility, and plastic working the coated substrate to cause plastic deformation of the metal substrate, thereby embedding the ceramic particles in a surface layer of the metal substrate. Optionally, ceramic material having bio-compatibility is coated over the surface of the ceramic particle embedded substrate. A composite implant exhibiting a firm bond is thus obtained.
