| Popis: | Titanium cylinders with radial graded porosity, which are potentially suitable for biomedical applications (replacement of cortical and trabecular bones involved in different joint and dental restorations), have been developed by a novel uniaxial and sequential compaction device, based on powder metallurgy techniques. The macrostructural, microstructural and mechanical properties of the cylinders were characterized. The microstructure obtained is a new bio-inspired/bio-mimetic approach to solving one of the most important drawbacks of titanium implants, i.e., bone resorption due to the stress-shielding phenomenon. In addition, the developed device has proved to have unique advantages in customizing the structural integrity in conventional powder metallurgy manufacturing in a simple, economic and reproducible manner.
