Biocompatible Ti-based materials with graded porosity

The Ti-based alloys with porous surface layers are prospective materials for biomedical implants. The porous layer promotes strong consolidation of the implant due to invasion of the bone tissue into the pores. Sharp interface between the porous and poreless materials can, however, become a stress concentrator that weakens the whole junction. In this work, we create gradually distributed porosity, pore size and Ti grain size within the porous layer, in order to smooth the transition between bone tissue and bulk Ti alloy. Spark plasma sinthering (SPS) method was used for consolidation of the functionally graded materials, where “space holder” particles (NaCl, MgO, etc.), created open porosity with the pre-determined gradient.
