Laser Additive Manufacturing System Modification for High-Level Entropy Alloys

The surface properties of aerospace components and coatings must be excellent throughout various temperatures. Steel, aluminum, copper, and high-level entropy alloys were employed to improve the external features of these components. This research used laser additive manufacturing to create functional high-level entropy alloys on an austenitic stainless-steel baseplate and to measure the influence of the laser parameters and density on the hardness and morphology of the produced alloys aimed at aerospace industries. Microstructure, as well as hardness, were studied as a function of experimental factors, laser power as well as scan speed. The data revealed that the coatings predictably stuck to the baseplate. Next to a preheat temperature of 400 °C, the best processing parameters, including individual alloys with defects of free structures, were 1200-1600W, 8–12 mm/s, and layers consisting of face-centered cubic and body-centered cubic structure phases. The quality, as well as the hardness of the belongings of alloys, were affected via the experimental factors. According to the findings, enhanced laser settings by increasing the preheating temperature increased the performance of alloys with prospective coatings and structural materials.
