Abstract: An electric spark strengthening device for metal planar repairing was studied. Through SEM analysis, MM200 wear test and hardness gradient distribution analysis, the strengthened repairing layer obtained by the device is relatively complete and has a certain thickness, which greatly improves the hardness and wear resistance of the part surface.

Key words: electric spark strengthening, planar repairing, SEM image, wear resistance, microhardness
