Effect of heat treatment atmosphere on the structure and apatite-inducing ability of Ca, P, Si and Na incorporated microarc oxidation coating on titanium
MAO coated Ti has been heat treated in different atmospheres to improve bioactivity. Flower-like rutile particles are formed on the MAO surface after heating in Ar at 800 °C. The difference in O source is key factor for the formation of particles. Attributing to the element diffusion, oxidized β-Ti prior grows along the discharge channel.
