Bioactive glass–ceramic with various zirconia concentrations was applied on stainless steel ( SS ) by the sol–gel method. Bioactive glass powder was prepared by the sol–gel method, and thermal properties of the prepared powders were studied by differential thermal analysis ( DTA ). The effects of zirconia were investigated to explore the growth of nanowires. The growth model of nanowires, in this study, is proposed in terms of the surface diffusion. The coatings showed the hardness values to be in the range of 3000–4500 MP a. The hardness values of prepared composite coatings increased with an increase in zirconia amounts.
