The invention relates to a bioceramic coated apparatus and method of forming the same. The apparatus may be a medical implant such as, for example, an orthopedic implant or a dental implant. The bioceramic coating is designed to increase tissue and/or bone growth upon implantation of the apparatus. The apparatus has a valve metal substrate having a nanoporous valve metal oxide surface layer. The nanoporous surface layer contains a plurality of nanopores. The nanopores have adsorbed phosphate ions on at least their interior surfaces. A bioceramic coating is formed on the nanoporous surface and anchored into the nanopores. Optionally, the nanopores are formed into a tapered shape in order to increase adhesion to the bioceramic coating.
A bioceramic coated apparatus, comprising:
A method for forming a bioceramic coated apparatus, comprising the steps of:
A method for forming a nanoporous surface on a surface of a valve metal, comprising the step of:
A valve metal substrate comprising a nanoporous valve metal oxide surface layer containing a plurality of nanopores, wherein the nanopores have adsorbed phosphate ions on at least their interior surfaces.
A valve metal substrate comprising a nanoporous valve metal oxide surface layer containing a plurality of nanopores, wherein the nanopores have adsorbed phosphate ions on at least their interior surfaces and the nanopores have a substantially tapered shape such that a bottom portion of the nanopores is wider than a top portion of the nanopores.
