Summary:

During fatigue testing of prototype austempered ductile iron crankshafts, cracks formed along crankpin fillets. These cracks were not detected by the conventional magnetic particle method but were readily imaged by a modified version of the gel electrode technique. The crankshaft was coated with a thin (0.5 μm) polymer film, either prior to, or after, the fatigue test. When the surface was subsequently inspected with a gel electrode probe, an impressed current from the probe flowed preferentially to the fatigue sites. Information is displayed in two formats:
