Abstract
Laser-directed energy deposition (LDED) is a newer way of making things that builds solid parts from metallic powder one layer at a time. The LDED process is more convenient compared to other metals synthesis processes because of its own merits such as minimum building time and greater powder deposition rate. The directed energy deposition machines can be programmed to use a specialized set of settings to process various grades of metallic powder. This process is mostly used for repairing metallic components. Inconel 718 is a superalloy used in high-temperature applications. In the present study, the LDED technique is used to synthesize the Inconel 718 superalloy. The experimental investigation examines the influence of powder feed rate and laser energy density on the geometry and quality of the single tracks deposition of Inconel 718 superalloy.
