Important results from the project
** Denna text är maskinöversatt ** The main technical contributions to the project from the GKN side are described below: Advanced process development of manufacturing technology for repair: Development of finishing for Ti 6Al 4V repaired components: Characterization of materials and raw materials: Mechanical testing
Expected long term effects
** Denna text är maskinöversatt ** This study has established that the DED process for Ti6Al4V material can be successfully used for repair operations. Although process parameters, the quality of powder, significantly affect the quality, the DED technique was observed to be robust, providing high-quality dense build-up over a wide process window. Post heat treatment, further improves the properties
Approach and implementation
** Denna text är maskinöversatt ** The results of this study show that DED powder is a promising process, but many new challenges are found and further exploration is needed. Although the post-treatment provided better properties, the quality of the raw material may affect the life of the repaired part The work carried out as part of the project has led to the following: Two theses:
