Abstract : Equipment development for the investigation of corrosion-fatigue mechanisms is described. Mini-probe arrays have been constructed to mount alongside and close to a fatigue-loaded specimen facing the advancing crack path. The purpose of a mini-electrode array is to measure electrochemical parameters (pH and potential) associated with an advancing fatigue crack. Equipment to apply fatigue loading to rectangular metal specimens has also been constructed. Further development work is required in order to use the equipment for the investigation of corrosion-fatigue phenomena. (Author)
