dc.description.abstract The aim of this work is to study the effect of halide treatment in powder metallurgy Ti-6Al-4V alloy, in order to improve high temperature oxidation and electrochemical corrosion resistance. Halide treatment was performed by immersing samples in a powder mixture containing 3 wt% NH4Cl, at 200 degrees C and 950 degrees C. Oxidation resistance was assessed by exposure to 600 degrees C for 300 h. The microstructure and phase constitution of the formed oxide layers was characterized. Corrosion resistance in aircraft simulated environment was evaluated with electrochemical impedance spectroscopy. Notable improvement in oxidation and corrosion resistance was observed for samples treated at 200 degrees C.
