The orthopedic implants are made of bio-compatible stainless steels or titanium based alloys. However, none of these materials is as capable for faster tissue or cell growth on the implants as compared to natural bone surface. Keeping in view of the natural bone compositions (hydroxyapatite and its group compound along with collagen fiber reinforcement), this work reports the development of a bio-compatible coating of CNT reinforced hydroxyapatite and its group compound through electrodepositions. The deposited coating (thickness ~ 80 micrometer) consists of both crystalline and amorphous phases (around 30%). The vacant space created by dilution of amorphous phase on interaction with body fluid, initiate tissue growth inside the coating and thus enhances the bonding between implant and tissues. The crystallite size was found to be in between 15 to 70 manometer. Different morphology of coating along with varying micro roughness and lattice strain were observed at various current densities.
