Research Abstract

This work has explored a new engineering method and process to repair the fatigue cracks in heat resisting Ni-based superalloys, combining the stress field assisted diffusion phenomenon and a micro-spark coatings. A series of the experimental works showed that the proposed method was very successful for the repair of the fatigue cracks which were artificially reproduced under the laboratory conditions. These results were summarized into a new damage map showing what in-service condition(s) is(are) more effective to which the proposed repair method is applied.
