Research progress of titanium alloy scaffolds and its surface modification technology

3D打印制造出的Ti-6Al-4V多孔支架相比传统的钛合金支架,力学性能更加接近天然骨组织,具有很好的生物相容性,有望成为骨缺损修复的理想材料。为提升钛合金的生物性能,各种表面处理技术应运而生,这些处理技术可分为涂层法和非涂层法,而不同的表面处理技术各有优劣,本文就钛合金支架及其表面处理技术的研究进展进行综述。

Compared with traditional titanium alloy scaffolds,the mechanical properties of Ti-6Al-4V porous scaffolds fabricated by 3D printing are closer to natural bone tissue and have good biocompatibility,which is expected to become an ideal material for bone defect repair.In order to improve the biological properties of titanium alloy,various surface treatment technologies emerge as the times require.These treatment technologies can be divided into coating and non-coating method,and different surface treatment technologies have their own advantages and disadvantages.This paper reviewed the research progress of titanium alloy scaffolds and their surface treatment technologies.
