In this research, the growth of bioglass (BG) (45S5) incorporated oxide layer via plasma electrolytic oxidation (PEO) method was studied with respect to different sodium hydroxide (NaOH) concentrations (0.1, 0.3, 0.5, and 0.7 M). The voltage response during the deposition process was highly dependent on the electrolyte concentration. Large sparks were recorded at the lowest electrolyte concentration. The result also showed that the increment of electrolyte concentration improved the thickness and mechanical properties of BG-coated pure titanium (TI) surfaces via the PEO process. However, the morphological investigation showed that the coating formation and the uniformity of coating distribution are dependent on the optimum concentration of the electrolyte. This study demonstrates the feasibility of the PEO method in producing a uniform bio-functional coating for biomedical applications.
