Carbon nanotubes (CNTs) possess excellent mechanical properties for their role playing in reinforcement as imparting strength to hydroxyapatite (HAp) coating. This work reports the electrodeposition of HAp/CNTs coatings on Ti6Al4V substrate at scanning potentials range of 0÷‐2.0 V/SCE, 5 mV/s, 5 scans at 45°C with the different functionalized CNTs concentration. The characterizations of the coatings were investigated. The amount of functionalized CNTs was determined using thermal gravimetric analysis. The X‐ray diffraction results showed that HAp/CNTs nanocomposite coatings were composed of HAp and CNTs. The diffraction peak with the highest intensity found at 2θ about 32 o corresponding to the (2 1 1) HAp crystal and the peak at 26.3 o can be assigned to (0 0 2) plane of CNTs. The HRTEM image confirmed the presence of CNTs in the coatings and CNTs amount of 7.25 % by TGA result.
