Abstract

In this research, the cell viability is tested on the surface-modified implants. Electrochemical setup is used for coating the hydroxyapatite (HA) powder and nano zinc particle (Zn)n on the Ti-6Al-4 V alloy. The electrolyte is prepared by mixing the HA and (Zn)n of varying quantity, and the effect of electrochemical parameter on surface coating thickness, surface quality and cell viability was studied. Based on the study, the cell viability is observed to be maximum at HA and (Zn)n concentration of 6 g/L and 0.8 g/L, respectively. The (Zn)n concentration in the range of 0.8 to 1.2 g/L and voltage of 12–13 V is suitable for obtaining the controlled coating thickness. During the electrochemical process, the nanopores HA structures with a pore size of 215–786 nm are obtained attributes for better cells attachment on the surface. The cell viability is found high (0.366) at 6 g/L HA and 1.6 g/L of (Zn)n concentration at 14 V.
