| 摘 要： | 采用射频磁控溅射技术在表面纳米化316L不锈钢基体上制备掺钽TiO2薄膜,研究了不同掺钽量对表面纳米化316L不锈钢基TiO2薄膜形貌、结构、亲水性和生物活性的影响规律。结果表明掺杂适量的钽能够细化TiO2薄膜颗粒;掺钽能够改善TiO2薄膜的亲水性和生物活性;含钽36%的TiO2薄膜表面自由能比未掺杂时提高了30.1mN/m,在SBF溶液中能促进羟基磷灰石在其表面晶化。

| Abstract: | Ta-doped TiO2 films were deposited on surface nano-grained 316L stainless steel by RF reactive magnetron sputtering technology.The morphology,structure,hydrophilic ability and bioactivity of TiO2 films with different doping density of Ta deposited on surface nano-grained 316L stainless steel were researched.The results show that the certain doping density of Ta can refine the grains of TiO2 film;Ta-doped TiO2 films deposited on surface nano-grained 316L stainless steel have better hydrophilic ability and bioactivity;the surface free energy of TiO2 film with 36% Ta-doped increased 30.1mN/m;TiO2 film with 36% Ta-doped can promote the crystallization of hydroxylapatite on TiO2 films soaked in simulated body fluid. |
