【 摘 要 】

A series of Mg–Ti composites are fabricated by high-pressure solid-state sintering (HPSSS) technique developed in our lab. The correlation between microstructures and corrosion behaviors is comparatively studied. It is shown that the Mg/Ti interface primarily determines the corrosion resistance of the composites, and the corrosion process is a comprehensive action of material composition, interface content, corrosion potential and interfacial oxide. Besides, the present semi-degradable Mg–Ti composites retain superior structure stability after Mg degradation due to the strong interfacial bonding obtained by the high-pressure solid-state sintering. All of the derived porous Ti exhibits a superior compressive plasticity, and the mechanical properties of the porous Ti can be readily adjusted by tuning the porosity. With superior mechanical properties, low Young's modulus and favourable pore size, the present porous Ti offers superior mechanical compatibility, demonstrating promising prospect in the load bearing biomedical applications.
