Title:
ELECTROLYTIC DEPOSITION OF COATINGS FOR PROSTHETIC METALS AND ALLOYS
Document Type and Number:
WIPO Patent Application WO2002059395
Kind Code:
A3
Abstract:
An article coated with an electrolytically deposited bio-compatible composite layer useful as an internal prosthetic device is disclosed. The bio-compatible composite coating that is electrolytically deposited onto the article comprises hydroxyapatite and chitosan. The introduction of chitosan into the crystal matrix of brushite/hydroxyapatite significantly improves the adhesive and chemical and mechanical stability properties of the coating.
