Preparation of K2Ti6O13/TiO2 bio-ceramic on titanium substrate by micro-arc oxidation
Source abstract
Abstract
K2Ti6O13/TiO2 bio-ceramic coatings are prepared successfully by micro-arc oxidation on titanium substrate in pure KOH electrolyte solution. The coating is prepared at various applied current density (150–500 mA/cm2) and in KOH electrolyte with different concentrations (0.5–1.2 mol/L). The composition and surface morphologies of coatings are strongly dependent on the applied current density and the electrolyte concentration. On the condition of lower current density and electrolyte concentration, K2Ti6O13 phase almost cannot be formed. The phase is mainly composed of rutile and K2Ti6O13 with increasing current density and electrolyte concentration. The surface morphologies are composed of whiskers and porous structures. The ability of K2Ti6O13/TiO2 bio-ceramic films inducing apatite deposition is evaluated by soaking it in biological model fluids. The results show the K2Ti6O13/TiO2 bio-ceramic coatings possess excellent capability of inducing bone-like apatite to deposit.
