Abstract: ABSTRACT OF THE INVENTION The present invention relates to a multifunctional bioactive hybrid composite coating system (m-SAF-C) tor titanium-based biomedical implants. The coating comprises biogonic hydroxyapatite (HAP) derived from caprine femur bone, furfural-modified sodium alginate (SAF), and 5-amino 4- imidazolecarboxamide (AICA), forming a stable organic—inorganic hybrid composite. The furfural modification of sodium alginate enhances the structural integrity and degradation resistance of the polymer matrix without the need for synthetic polymer reinforcement. The hybrid composite is deposited onto surface activated titanium substrates using electrophoretic deposition to produce a uniform and adherent coating. The resulting coating exhibits improved surface roughness, controlled wettability, enhanced microhardness, reduced degradation under physiological conditions, improved corrosion resistance, and antibacterial activity compared with conventional hydroxyapatite coatings. The coating maintains the crystalline apatite phase while providing a mechanically stable and bioactive interface suitable for load-bearing biomedical implant applications. The invention provides a sustainable, naturally derived hybrid coating platform capable of improving the long-term performance and functionality of metallic implants. Keywords: Biogenic hydroxyapatite; Furfural-modified sodium alginate; Hybrid composite coating; Titanium implant coating; Surface engineering.
