【摘要】 分别用喷丸酸蚀(SLA)、阳极氧化(AO)以及复合喷丸酸蚀和阳极氧化(SLA+AO)方法对纯钛进行表面改性,以获得具有分级多孔微纳结构、表面富氧及锐钛矿相的钛表面特征。通过表面形貌、粗糙度、表面成分以及晶相结构来分析各组样品的表面特征及其形成机制。喷丸酸蚀(SLA)处理之后的样品具有由2～3μm凹坑和100～400nm孔洞组成的分级多孔形貌特征。阳极氧化(AO)处理之后的样品表面形成分布较均匀的20～400nm的孔结构,表面富氧并出现锐钛矿相。复合喷丸酸蚀和阳极氧化(SLA+AO)方法处理之后的样品表面具有分级多孔微纳结构,表面富氧并出现锐钛矿相。最后分别探讨了SLA、AO及SLA+AO处理方法的形成机理。更多还原

【Abstract】 This manuscript modifies titanium surface through sandblasting & acid etching(SLA),anodic oxidation(AO) and composite process(SLA+AO) for achieving the surface features with micro-nano porous structure,oxygen-rich and anatase structure.Analyze the surface characteristics and formation mechanism of each group samples through surface morphology,surface roughness,surface composition and crystalline structure.The surface morphology of samples with SLA process was formated by 2-3μm pits and 100-400nm holes.Besides oxygen-rich and anatase structure,uniform 20-400nm pore structure distributes on the surface of samples with AO process.While samples with composite(SLA+AO) process has micro-nano porous structure like group SLA samples and also oxygen-rich and anatase structure like group AO samples.更多还原
