1. Aspects Regarding Alloying Effect on Electrochemical Stability of Sintered Titanium
The titanium alloys Ti6Al4V, Ti5Al2.5Fe and Ti6Al7Nb sintered in high vacuum, about 10-3 Pa, at 1300oC, of element powders with 200μm grain size presents spontaneous passivation in Ringer solution and submicron corrosion rate, higher electrochemical stability properties than sintered pure titanium. Titanium alloying improves the sintering quality, achieving thus a reduction of the material porosity by 10 ÷ 20% and a corresponding increase in mechanical
