Description
Due to their outstanding properties in terms of wear and corrosion resistance, as well as their excellent mechanical properties, AMC materials are considered exceptional lightweight construction materials and contribute to increased resource efficiency in numerous applications through consistent weight reduction.
To enable their use in additive manufacturing, AMC materials must be available in a suitable form. Powder, wire, or rod-shaped feedstocks are often the standard. The production of corresponding rod-shaped AMC semi-finished products by casting in permanent molds or via continuous casting currently poses a major challenge due to insufficiently understood process-microstructure relationships.
The goal of the project is to fill these knowledge gaps in order to provide high-quality, rod-shaped AMC materials with varying sizes and proportions of SiC reinforcement. These rods then serve as the starting material for the production of AMC composite powders via ultrasonic atomization. This makes the AMC materials suitable for a wide range of additive manufacturing processes.
Finally, the produced AMC powder materials are processed via laser beam cladding to produce wear-resistant coating systems.

Conclusion
Laser Cladding is expected to facilitate and, above all, expand the processability of AMC composite powders. This will open up new markets and areas of application that will continue to positively transform lightweight construction.
