【 摘 要 】

We study the possibility of restoring the blades of chromium-nickel materials for the repair of parts of gas turbine engines using selective laser melting technology. The stages of preparation of the items to repair and reconditioning are considered in detail, the algorithm of the recovery process to a 3D machine has been developed. Chemical analysis of the raw material and facing material has been performed. Maps of distribution of chemical elements in the fusion zone of the starting material with the surfacing material have been acquired. In order to study the nature of alloying materials fractographic analysis of the places of fusion was performed. A map of distribution of chemical elements in the fusion zone was obtained.
