摘要: 研究了一种用于金属平面的电火花强化修复装置。经过SEM照片分析,MM200磨损试验,以及硬度梯度分布综合判断,该装置生成的强化修复层比较完整、有一定厚度,极大改善了零件表面的硬度和耐磨性。

关键词: 电火花强化, 平面修复, SEM形貌, 耐磨性, 显微硬度

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
