Abstract
A system is configured to treat a conductive component. The system includes a power source, an interface configured to electrically contact with a surface of the conductive component, and a controller coupled to the power source and the interface. The controller is configured to pass electric current (e.g., electric pulses) from the power source through the interface and the component to melt tips of a set of cracks along the surface of the component. As the current passes around the set of cracks, the current generates localized heating in high-resistance dislocations at the crack tips to repair the cracks. Accordingly, such current heals the cracks and inhibits the cracks from spreading. Furthermore, the effect of the current remains localized thus enabling the current to strengthen the material around the cracks while easily avoiding damaging or weakening other portions of the component.
