采用室温直流反应磁控溅射技术在纳米晶体钛表面制备掺钽TiO2薄膜,研究了掺Ta量对纳米晶体钛基TiO2薄膜摩擦磨损性能的影响。结果表明：在室温模拟人体体液条件下,掺钽TiO2薄膜与不锈钢淬火钢球（Φ4mm）对摩的磨损率为10^-6-10^-5mm^3·m^-1 N^-1级;随着Ta含量的增加,薄膜的摩擦系数和磨损率呈先减小后增加的趋势,掺Ta量（质量分数）为22%Ta的TiO2薄膜具有最低的摩擦系数（0.20）和磨损率（1.5×10^-6mm^3·m^-1·N^-1）。具有良好的抗磨性能与其硬度与弹性模量比高、抗腐蚀性强和摩擦系数低一致。
The friction/wear properties of TiO2 films with different Ta-doped content deposited on surface of nano-grained Ti by DC reactive magnetron sputtering technology at room temperature were investigated.The results show that the Ta-doped TiO2 films exhibit the specific wear rate on the order of 10^-6-10^-5mm^3·m^-1·N^-1 sliding against a stainless steel quenched ball（2 mm in radius） at room temperature by simulation body fluid.With the increasing Ta content in TiO2 films,the friction coefficient and wear rate of TiO2 films were gradually decreased and then increased.And the TiO2 film with about 22%Ta-doped has the smallest friction coefficient（0.20） and wear rate（1.5×10^6）mm^3·m^-1·N^-1）.The good wear-resistance of the TiO2 films with about 22%Ta-doped is in accordance with its high hardness-to -modulus ratio,good corrosion-resistance and low friction coefficient.
