Abstract
Remanufacture engineering is an emerging industry that saves resources as well as protects the environment. However, cracks on remanufactured components can result in serious trouble. Therefore, in order to avoid unnecessary waste of resources and energy, these cracks should be repaired radically in order to ensure the smooth progressing of the remanufacturing process. Consequently, the crack healing technique of metal materials is very important in the field of remanufacturing. In this study, the U-shape vane stainless steel of a centrifugal compressor which had cracks was processed by pulse current using a high pulse current discharge device, and the influence of the streaming effect and Joule heating effect of pulse current on the crack healing of metal materials was studied, aiming to provide references for the better application of this technology in the remanufacturing field in the future.
