Abstract:Additive manufacturing (AM), or 3D printing, provides a new and challenging approach towards mold-free product manufacturing through a layer-by-layer deposition of thin layers. State-of-the-art metal AM is mostly fusion based allowing complex product shapes to be realized. Unfortunately, the materials microstructure is often non-homogeneous and suffers from porosity and residual stresses. Only a limited number of alloys can be employed due to solidification related problems, such as cracking. A new and promising approach to extend the range of alloys applicable and to improve the microstructure of the manufactured product is based on solid stage deposition. Within this research project the possibilities and limitations of solid state additive manufacturing have been investigated. The manufacturing process is based on the friction surface cladding process developed within the PT research chair. Here, frictional heating and compressive forces are used to enable controlled deposition of thin layers on a substrate in the solid state. The aim of this study was to understand the bonding process of the added metal on the substrate and to find the important parameters that determine the bonding quality. The research concentrated on the deposition of a high strength aluminium alloy 2024-T351 typically used for aerospace applications.
