Processing and Characterization of Bilayer Materials by Solid State Sintering for Orthopedic Applications

A new processing route is proposed to produce graded porous materials by placing particles of Ti6Al4V with different sizes in configurations obtain bilayer samples that can be used as bone implants. The sintering behavior studied dilatometry and the effect layers’ configuration established. To determine pore features, SEM computed microtomography were used. Permeability evaluated numerical simulations 3D real microstructures mechanical properties are compression tests. results show a porosity obtained function size particle anisotropy due distribution kinetics, changed layer arrangements. Young modulus yield stress depend on relative density roughly predicted power law, considering behavior. intimately related median leads smaller coarser particles. It concluded specific characteristics, radial being most promising for biomedical applications.
