Paper Title:
Porosity Study of Sintered Titanium Foams
  Abstract

Titanium foams have been used for surgical implants and biomedical engineering because they exhibit inert behavior and good corrosion resistance. Substantial progress has been achieved for metallic foam fabrication techniques, however the porosity characterization methods available haven’t been studied sufficiently. A previous research has developed a powder metallurgy route to produce pure titanium foams attaining the porosity requisites for porous surfaced surgical implants. In this study, titanium foams porosity was evaluated employing different techniques: optical quantitative metallographic analysis with automatic image technique, gamma-ray transmission and x-ray microtomography. These techniques can be used for titanium foams analysis, though their results can not be simply compared, because they use quite different methodologies and take different measurement assumptions.
