中文摘要:
      首先采用含氟电解液对Ti6Al4V基体进行阳极氧化预处理,然后通过水热电化学法在其表面制备羟基磷灰石(hydroxyapatite,HA)涂层。研究了阳极氧化电压对基体表面物相、形貌、润湿性和表面粗糙度(Ra)的影响;同时,还研究了阳极氧化电压对HA涂层物相、形貌以及涂层和基体结合强度的影响。结果表明:经过阳极氧化后的Ti6Al4V基体表面生成了孔洞状TiO2纳米管,并且管径随氧化电压的增大而增大;在电压为25 V时,基体Ra为0.5 μm,而且基体与模拟体液的接触角明显降低;水热电化学沉积得到的HA涂层呈现出分层生长的模式;阳极氧化预处理的基体和涂层间的结合强度明显提高,并在阳极氧化电压为25 V时达最大,为20.0 MPa。
英文摘要:
      Ti6Al4V was firstly pre-treated in fluorine-contained electrolyte by anodic oxidation, and then hydroxyapatite coating was prepared on its surface by hydrothermal-chemical method. The effects of anodic oxidation voltage on the phase, morphology, wettability and roughness of the Ti6Al4V surface, on the phase and morphology of the HA coating, and on the bonding strength between coating and substrate were studied. The results show that porous TiO2 nanotubes are synthesized on the Ti6Al4V surface. The diameter of the tube increases with the increase of oxidation voltage. When the voltage is 25 V, the surface roughness (Ra) of the substrate is 0.5 μm with the contact angle between the matrix and the simulated body fluid significantly decreased. The HA coating obtained by hydrothermal electrochemical deposition exhibits a stratified growth pattern. The bonding strength between substrate and coating is significantly improved by anodic oxidation. At the anodic oxidation voltage of 25 V, the bond strength reaches the maximum value approximate 20.0 MPa.
