                         superficial treatments in the mechanical and corrosion resistance 
                         Ti-6Al-4V alloy. It was used a Ti-6Al-4V alloy in cylindrical bars 
                         forms, forged condition and annealing at 190 oC for 6 hours and 
                         cooled in air. Three different conditions of heat treatments were 
                         utilized to obtain the following microstructures: 
                         Widmanst{\"a}tten, Martensite e Bimodal. It was also analyzed 
                         samples with superficial treatment of Plasma Immersion Ion 
                         Implantation (PIII) process and ceramic coating by plasma spray. 
                         In the PIII treatment the samples was put in a vacuum reactor 
                         (76x10-3 Pa) and implanted by nitrogen ions in time intervals 
                         between 15 and 120 minutes. Yttria (8 wt.%) stabilized zirconia 
                         (YSZ) with a CoNiCrAlY bond coat was atmospherically plasma 
                         sprayed on Ti-6Al-4V specimens. Constant load creep tests were 
                         conducted with Ti- 6Al-4V alloy at 600°C. The alloy with 
                         Widmanst{\"a}tten structure shows greater resistance to creep and 
                         oxidation with a longer life time in creep. Potentiodynamic 
                         corrosion tests in 0.9 % NaCl aqueous solution, pH 6.0, at room 
                         temperature (~25oC), were carried out on the Ti-6Al-4V alloys 
                         thermally treated and modified surfaces. Comparison between the 
                         corrosion parameters of the treated alloy and modified surface, 
                         showed that the anodic and cathodic current densities so simulate. 
                         This result suggests that the surface modified by PIII is also 
                         efficient in the protection of Ti-6Al-4V alloy against 
                         corrosion.",
