Calcium carbonate (CaCO 3 ) have a high biocompatibility and biodegradability due to their chemical similarity to human bone tissue. Electrophoretic deposition (EPD) is an advanced technique used for obtaining biomedical coatings. This research is, for the first time, to investigate the effect of voltage and duration on the CaCO 3 coatings obtained by EPD on nanostructured 316L SS surface. SEM images showed that the proportion of calcium carbonate particles in the coating increased significantly with higher applied voltages. Additionally, an increase in coating thickness ( ̴20 µm) was observed with longer deposition durations. The successful incorporation of CaCO 3 in all coatings was confirmed by SEM and XRD analysis. Also, AFM analysis confirmed that coated surface performed rougher topography and morphology. These findings suggest that bioactive CaCO 3 coated on nanostructured 316L surface is promising surface for biomedical applications.
