Develop MAR-M-247 Repair with Direct Energy Deposition (REP-MAR)

Important results from the project

The project provided valuable insights into how DED and HIP can be used for repairing MAR-M247. The goals were partially achieved; the project demonstrated that DED can be used to fill defects and that internal cracks can be eliminated. However, further process optimization for depositing MAR-M247 is required. The project demonstrated that both the process and the alloy have great potential in high-temperature applications, paving the way for future development.

Expected long term effects

The project is expected to lead to the development of new, efficient repair methods for MAR-M247, reducing material waste and energy consumption. This contributes to lighter and more durable high-temperature components, which are critical for future aircraft engines. Furthermore, the project strengthens collaborations and knowledge exchange, paving the way for continued research, innovation, and commercial applications in advanced alloys and manufacturing processes.

Approach and implementation

The project was implemented with a project team that had previously worked together, which contributed to an efficient working process. Priorities and changes were continuously implemented. Despite a relatively tight schedule, everything proceeded according to plan, although some budget adjustments became necessary as test results and evaluations guided the next step. Overall, the project developed as planned with flexible adaptations, and the collaboration worked very well.
