An Investigation into the Stages of Alloy 625 Crevice Corrosion in an Ocean Water Environment: Initiation, Propagation and Repassivation in a Remote Crevice Assembly

In this paper we investigate the initiation, propagation and repassivation of alloy 625 crevice corrosion in ASTM artificial ocean water using a remote crevice assembly. This assembly was equipped to monitor crevice corrosion current at a constant potential and consisted of two alloy 625 washers fastened together at a set torque (gap) with an alloy 625 nut and bolt. Applied potential controlled initiation time with higher potentials having a...
