Abstract: A crack arresting experiment is conducted with a ZL-2 super pulse discharge generator for components with transverse cracks, and then the component is repaired with laser cladding technology. The microstructure around the crack tip is compared before and after discharging, then the wear resistance experiment is conducted on specimens before and after laser repairing. The results show that its wear resistance after laser repairing can be significantly improved. Finally, mechanical properties of specimens before and after repairing are compared, it shows that the mechanical properties of specimens after discharging and laser remanufacturing can be improved considerably. Thusly, the remanufacturing purpose is realized.
