| 英文摘要 | Porous titanium alloys have been used for biomedical implants owing to their low-modulus matching with that of human bones and interconnecting pores with suitable size, which facilitates bone ingrowth and satisfies the requirement of a successful implant. Recently, additive manufacturing (3D printing) has emerged as an excellent technology for manufacturing porous implants with accurate designed pore parameters and overcoming processing difficulties caused by high melting temperatures of metals. In this paper, the microstructure and mechanical properties of porous Ti-6Al-4V, commercial pure titanium (CP-Ti), and low-modulus Ti2448 alloys produced by 3D printing, obtained mainly by the authors.. group, are reviewed. For Ti-6Al-4V, its fatigue properties are affected by the type of mesh struts and post processing. The better fatigue life of CP-Ti compared to that of Ti-6Al-4V derives from its superior ductility and the strain hardening effect caused by deformation twins. The excellent fatigue life of the lowmodulus Ti2448 alloy results from its superelasticity and the high toughness, which increases the crack nucleation life and fatigue crack propagation life, respectively. Future directions of corrosion-fatigue properties of materials in complex physiological environments, surface biological functionalization, and porous material of new metallic alloy systems are discussed. |
