医用多孔钛合金表面改性技术研究进展
Research progress of surface modification techniques of porous titanium alloy for medical use
摘要
Abstract
Porous titanium alloys have good mechanical properties,which can reduce the"stress shielding"effect and promote the bonding with biological tissues,but there are still deficiencies in their functionalization.Surface modification can be achieved by modifying the surface morphology of the material or loading functional components on the material surface,thereby imparting good functional properties such as osteoblastic,antimicrobial and corrosion/abrasion resistance.Unlike dense titanium materials such as titanium plates/bars,porous titanium has a complex internal structure,and thus its modification is mostly carried out in fluid(liquid,gas)media to achieve good cladding properties.This paper is categorized according to the principle of surface modification and the nature of the functional components,focusing on surface modification methods and effects of the traditional and new medical porous titanium alloys,and the advantages,disadvantages and influencing factors of different methods are summarized and analyzed,aiming to provide guidance for the surface modification of medical porous titanium alloys.关键词
