This paper investigates the effect of various sintering temperatures from 800 to 1500°C on the microstructure evolution of cp-titanium processed by Spark Plasma Sintering (SPS). The material processing conditions under consideration may change the obtained atomic order and microstructure. The different relation of the mechanical and corrosion resistance properties observed in the analyzed results could at the same time be shaped in the expected range. The SPS procedure allows the obtainment of nearly theoretical densities of the compacts and excellent mechanical properties (UTS=892MPa, CS=1442MPa). The results confirm that the contact angle measurement could support the process control, particularly if a microstructure feature is considered.
