A technique to heal a fatigue crack for a stainless steel by controlling a high-density electric current field was studied. The high-density electric current was applied at the crack tip using electrodes. A surface-activated pre-coating technique was used in order to improve adhesion of the crack surface. The crack on the specimen surface was observed by scanning electron microscope (SEM) before and after the application of the high-density electric current to examine the effect of the fatigue crack healing. The experimental results showed that the fatigue crack was closed and the crack growth rate of a healed specimen was decreased by the electrical stimulation.
