阳极氧化 Ti 6Al 4V 合金表面 TiO2多孔膜的制备及研究
Preparation and Study of TiO2 Porous Film on the Surface of Ti-6Al-4V Alloy by Anodic Oxidation
摘要
Abstract
Ti-6Al-4V alloys were anodized in H2SO4 solution.The study was to investigate the effect of anodic oxidation parameters(the anodizing voltage,the oxidation time and the concentration of sulfuric acid)on the morphology,phase,wettability and surface roughness of Ti-6Al-4V substrates.The results indicated that TiO2 porous oxide films consisting of annatase and rutile phases were achieved directly on the surface of Ti-6Al-4V substrates after anodic oxidation.In 0.5 mol·L-1 H2SO4 solution,the pore size of the titania layer increased with the anodizing voltage increased.The contact angle on the surface of Ti-6Al-4V decreased obviously after anodic oxidization treatment,and the contact angle of the sample at 120 V had dropped to about 16.9 degree from 52.8 degree,which has good wettability.Moreover,the roughness increased with the increase of voltage and reached about 0.56μm at 120 V.The content and the pore size of TiO2 porous oxide film increased gradually with the increasing of the oxidation time and the concentration of sulfuric acid.The wettability and surface roughness of substrates were also improved,which reached the best for 10 min or in 0.5 mol·L-1 H2SO4 solution.The oxide films were damaged when the oxidation time was longer than 10 min or the concentration of sulfuric acid was higher than 0.5 mol·L-1 .关键词
