Abstract:
    Production of titanium and titanium alloy glass ceramic coating is carried out by mixing raw materials, drying, heating while melting, press to prepare glass, grinding into powder, adding into methanol to prepare slurry, sand blowing by alumina, immersing pure titanium, Ti6A14V, Ti29Nb13Ta4.6Zr and Ti24Nb4Zr7.6Sn alloy into mixed solution, leaching and high-temperature sintering to obtain the final product. The glass ceramic consists of CaO and P205 80-90mol%, Na2O 4-7mol%, TiO2 and ZrO2 residues. It is non-toxic, has better biological activity and binding ability. It can be used to induce implant surface bone growth.
