Electrochemical conditions within corrosion fatigue cracks are thought to exert an important influence upon propagation rate. For the case of cathodically polarized steel in sea water, it has been observed that pH of electrolyte adjacent to steel increased and calcareous material formed on the steel surface. As a consequence of the latter process the electrochemistry within cathodically polarized cracks may be unique compared to other electrolytes. The objective of this study has been to...
Show moreElectrochemical conditions within corrosion fatigue cracks are thought to exert an important influence upon propagation rate. For the case of cathodically polarized steel in sea water, it has been observed that pH of electrolyte adjacent to steel increased and calcareous material formed on the steel surface. As a consequence of the latter process the electrochemistry within cathodically polarized cracks may be unique compared to other electrolytes. The objective of this study has been to measure the potential and pH within simulated fatigue cracks of ABS DH 32 steel under cathodic protection. In addition, the calcareous deposits which formed within the simulated cracks were observed and analyzed. Based upon these data, potential, pH profiles and calcareous deposit thickness and composition were measured. This, in turn, permitted conditions within the simulated crack to be better understood.
