Metallic orthopaedic implants lack uniform tissue growth over their surfaces after implantation on account of presence of multiple grain boundaries with varying surface energy. Keeping in view of natural bone compositions, this work reports the development of composite biocompatible coating through in-situ formation and co-deposition of hydroxyapatite and calcium phosphate phases along with polypyrrole with the help of electro deposition process. Different coating morphologies along with varying amount of hydroxyapatite phase and lattice strain were observed under various in-situ nucleation rates. These composite coatings are comprised of brittle hydroxyapatite scaffold along with polymer as filler material in between the scaffolds. Thus, this unique structure helps to increase the overall coating modulus of elasticity near to human bone along with higher corrosion resistance under contact with body fluid. Its exhibit superior biocompatibility as compared to bare metallic surfaces and can be used for faster and uniform tissue growth.
