Phase Contamination Characterization of Stepwise-built Functionally Graded Hydroxyapatite/Titanium (HA/Ti) Sintered under Various Atmospheres

Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD) test were utilized to detect the phase transformation of a HA/Ti Functionally Graded Material (FGM) prepared via Powder Metallurgy (PM) technique. The effects of oxygen (O2), nitrogen (N2), forming (N2+H2) and Argon (Ar) sint...
