The detection of crevice corrosion in titanium and its alloys through the use of potential monitoring

Conventional laboratory crevice corrosion testing requires approximately thirty days and is a simple go/no go test which does not indicate crevice incubation time and propagation. This study focuses on the effectiveness of potential monitoring to detect the onset of crevice corrosion and propagation for several titanium alloys in chloride environments. Utilizing this technique, crevice corrosion initiation is determined after several days, thus a shorter test period is required. This technique may well be suited for field as well as laboratory applications. Crevice corrosion incubation periods and corresponding potential behavior are investigated along with the effect of crevice to uncreviced surface area ratio. Under freely corroding conditions, which better simulate in-service conditions, the relationship between the corrosion potential (Ecorr) and crevice corrosion initiation and propagation was readily determined. Corresponding crevice corrosion initiation and steady state propagation surface morphology was also examined.
