摘要

提出了一种确定裂纹愈合电脉冲有效路径的方法，该方法采用单一控制参数-电流脉冲的比能量，而不是像以前那样使用多个参数。该方法对不锈钢带长疲劳裂纹的局部修复具有较好的效果。该方法既保证了裂纹边缘的焊接质量，又改善了试样的力学性能。

A novel approach to determining the parameters of electric pulse healing of fatigue cracks

An approach to determining effective route of electropulsing treatment (EPT) for crack healing is proposed using single control parameter - the specific energy of the current pulse, rather than several parameters as in the previously used. The developed multi-step route has proven its effectiveness in partial healing of long fatigue crack in a stainless steel ribbon. The suggested route ensures high quality of welding of crack edges and improves mechanical behavior of the healed sample.
