Abstract Scope |
Directed Energy Deposition (DED) is one of the categories in Additive Manufacturing (AM) that has increased our attention due to the technological advancements in recent years. Mainly, with advancements in laser power, application of multi-materials, and capability to print greater dimensions. We are experimenting with a particular process in DED, cladding. Cladding is the process of applying a metal coating to a substrate with the purpose of improving its properties, such as corrosion and material strength. For our experiment, we implemented a powdered feedstock (Inconel 718) which was tested in different types of substrates. This, in an effort to reduce the time spent on trial-and-error development of cladding parameters. We develop a procedure on how to determine a good clad interaction after an examination of the microstructure and interaction of single beads and a hatched area. |
