                         strength and creep-resistance properties for aerospace 
                         applications has led in the last decades to sustained research 
                         activities to develop new alloys and/or improve existing ones. 
                         Titanium and its alloys are excellent for applications in 
                         structural components submitted to high temperatures owing to 
                         their high strength to weight ratio, good corrosion resistance and 
                         metallurgical stability. Its high creep resistance is of great 
                         importance in enhancing engine performance. However, the affinity 
                         by oxygen is one of main factors that limit its application as 
                         structural material at high temperatures. Materials with adequate 
                         behavior at high temperatures and aggressive environmental became 
                         a scientific requirement, technological and economically nowadays. 
                         The objective of this work is the mechanical and microstructural 
                         characterization of the Ti-6Al-4V alloy after treatment by 
                         nitrogen Plasma Immersion Ion Implantation (PIII) process. The aim 
                         of this process is the improvement of superficial mechanical 
                         properties of the Ti-6Al-4V alloy. The selected alloy after ionic 
                         implantation process by plasma immersion was submitted to creep 
                         tests at 600°C, in constant load mode at 250 and 319 MPa. The 
                         techniques used in this work were optical microscopy and scanning 
                         electronic microscopy. The fractograph analysis of the samples 
                         tested in creep shows narrowing phenomena and microcavities. The 
                         creep results show the significant increase of material 
                         resistance, it can be used as protection of oxidation in high 
                         temperatures applications.",
