| Abstract |
On the basis of fault diagnosis of rolling bearings, further research on the subsequent treatment methods is necessary. This study developed a method of repairing surface defects of rolling bearings by Electropulsing Treatment (EPT) technology, and quantitatively analyzed the influence of current parameters on the repair of rolling bearings. The results showed that different parameters of
pulsed current have repairing effects on artificial surface defects of rolling bearings which serve as a
model for spalling damage. However, excessive current parameters can be detrimental, potentially
introducing adverse residual tensile stresses or causing material softening through over-tempering,
which compromises the bearing’s long-term performance. The height of surface asperities in the
defect area treated by pulse current decreases, which is attributed to the combined effects of intense
localized Joule heating and current-induced mass transport. The current crowding around the asperities significantly enhances these phenomena. The research results provide a new solution for the
repair of rolling bearing defects by EPT. |
