The main objective of here presented research is a design the scaffold/porous titanium(Ti) alloy based composite material demonstrating better biocompatibility, longer lifetime andbioactivity behaviour for load-bearing implants. The development of such material is proposed bymaking a number of consecutive tasks. Modelling the mechanical, biomechanical and biologicalbehavior of porous titanium structure and an elaboration of results is performed by mathematicalmethods, including FEM and fuzzy logic. The development of selected Ti-13Zr-Nb alloy withdesigned porosity and no harmful effects is made by powder metallurgy (PM) with and withoutspace holders, and by rapid prototyping with an use of selective laser melting (SLM). Thedevelopment of an oxidation technology resulting in high corrosion resistance and bioactivity iscarried out by electrochemical oxidation, gaseous oxidation and chemical oxidation, and theircombination. The HA depositon is made by electrochemical and chemical (alternate immersion)methods. The core material is designed as a combination of natural polymer and bioceramics inorder to allow slow dissolution followed by stepwise growth of bone tissue and angiogenesis,preventing local inflammation processes, and sustaining the mechanical strength close to that ofnon-porous material.
