Preparation and Mechanical Properties of a Novel Biomedical Magnesium-based Scaffold
Magnesium has been recently recognized as a biodegradable metal for bone substitute applications.In the present work,a novel magnesium based scaffold with a specific two-layer structure was prepared for powder metallurgical process.The outer layer of the scaffold shows an interconnected porous structure,so that the fresh fluid can be easily sent into the material,allowing the ingrowth of new bone tissue.The inner compact structure reinforced by the salt particles can increase the strength of the material.Structural characterizations and mechanical tests of the materials demonstrate that the structural and mechanical properties of the magnesium-based scaffold with an appropriate salt content prepared by the current method are quite comparable to those of cancellous bone.Therefore,the magnesium-based scaffold with such a two-layer structure has the potential to serve as degradable implants for bone substitute applications.
