摘要:

醫用多孔金屬材料，特別是多孔鈦及鈦合金能夠提供與人體骨組織相匹配的力學性能，并促進骨組織長入以提高其與骨的固定度，在人體硬組織修復與替換方面具有廣泛的應用前景。重點圍繞多孔鈦及鈦合金的制備方法及適用于其復雜孔隙結構的表面生物活化方法，綜述了各種方法在多孔鈦及鈦合金上的應用現狀。目前適用于多孔鈦及鈦合金制備的技術主要有粉末冶金法、鈦纖維燒結法、自蔓延高溫合成法、選區電子束熔化技術和選區激光熔化技術，適用于多孔鈦及鈦合金表面生物活化的技術主要有溶膠凝膠法、仿生礦化法、電化學沉積法和微弧氧化法。多孔鈦及鈦合金的力學相容性和表面生物活性需要同時滿足臨床要求，才能進一步擴大其在醫學領域的應用范圍。

Abstract:

Biomedical porous metal materials, especially the porous titanium and titanium alloys, can provide the mechanical properties similar to human bone and promote growth of bone tissue into pores of the materials to enhance the fixation between their implants and bone at early periods of implantation, exhibiting a great potential for the application of human hard tissue repair and replacement. This paper focuses on the preparation methods and research progress of porous titanium and titanium alloys and their surface bio�瞐ctivation technologies which are suitable for the complex pore structure. Nowadays, the main methods suitable for preparing porous titanium and titanium alloys include powder metallurgy (PM), titanium fibers sintering, self�瞤ropagating high�瞭emperature synthesis (SHS), selective electron beam melting (SEBM) and selective laser melting (SLM). Surface bio activation technologies suitable for porous titanium and titanium alloys, including sol�瞘el processing, bionic solution, electrochemical deposition, and micro arc oxidation, are also reviewed. As biomedical materials, both mechanical compatibility and surface bioactivity of porous titanium and titanium alloys must be achieved  to meet clinical criteria.��
