摘要：
Ti-6Al-4V biocompatible material to be used as an implant, fabricated by Electron Beam Melting, was investigated for mechanical properties namely hardness, grain size and porosity. Phase characterization was analysed by X-ray diffraction; morphological and micro structural features were assessed by Scanning Electron Microscopy and Optical Microscope respectively. The asproduced Electron beam melted Ti-6Al-4V sample had increased surface roughness and a thick surface oxide layer. The corrosion behaviour in simulated body fluid environment was compared for wrought and Electron beam melted Ti-6Al-4V samples by performing anodic polarization measurement using sequencer computer controlled potentiostat. The Electron beam melted sample had the corrosion rate of 0.0148 mils per year and wrought sample had 0.0196 mils per year. © (2015) Trans Tech Publications, Switzerland.
