Abstract

Corrosion behavior of three titanium alloys (TC4, TC18, TC21) in 3.5%NaCl solution was studied by means of cyclic voltammetry, SCC test with WOL pre-cracked sample and scanning electron microscope. Results showed that the pitting corrosion potential E_b of the three titanium alloys were 1.625, 1.671 and 1.871 V for TC4, TC18 and TC21, respectively. All values of E_b were high, representing the excellent pitting corrosion resistance of them. The pitting corrosion susceptibility of them could be ranked as the following descending sequence: TC4>TC18>TC21. The K_IS_CCfor TC4, TC18 and TC21 were 62.92, 66.82 and 71.99 MPam^0.5 respectively and the SCC susceptibility of the three titanium alloys followed a sequence as: TC4>TC18>TC21. On the fractured surface of the alloys after SCC test, a macro-morphology with three zones representing pre-crack, stress corrosion induced crack and mechanical fracture respectively were clearly differentiated, while the stress corrosion cracking zone showed mainly ductile fracture.

Key words: titanium alloy stress corrosion pitting corrosion stress field intensity factor cyclic voltammetry
