| Abstract: | 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 10-6-10-5mm3·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(1.5×10-6mm3·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. |
