Biomedical metallic materials such as stainless steel, titanium and it alloys have good mechanical properties and biocompatibiltity but do not posses bioactive behaviour. Therefore, biopolymers combined with bioactive inorganic fillers are being investigated to develop the bio-function behaviour and optimize the performance and biocompatibility (improve cell adhesion and proliferation) of metals [1, 2].  Electrophoretic deposition (EPD) has been identified as an economical and versatile processing technique for biopolymer and composite coatings at a low temperature for a wide range of biomedical applications [2]. This project investigates EPD based techniques for the deposition of biodegradable polymer-bioactive filler composite coatings for orthopedic applications.
