Electrochemical behavior of titanium alloys using potentiodynamic polarization

Abstract

Titanium is for aerospace production is of 80%. In an aircraft structure, 15% of the weight is titanium. The principal reasons to use titanium alloys are the save of weight, increase performance temperatures ratio and corrosion resistance. To analysed corrosion behavior of Ti alloys, polarization potentiodynamic cyclic was employed. Electrolytes used were H2SO4 and NaCl at 3.5% wt. The type of corrosion presented in Ti alloys was generalized in both electrolytes.
