Abstract: A method for fabricating a turbomachine component including a metal alloy with a layering device is provided. The method for fabricating the turbomachine component may include combining two or more elemental powders to form a powdered material. The method for fabricating the turbomachine component may also include forming a first metal alloy layer of the turbomachine component on a substrate. Forming the first metal alloy layer on the substrate may include melting a first portion of the powdered material to a first molten material with a heat source, mixing the first molten material with the heat source, and cooling the first molten material. The method for fabricating the turbomachine component may further include forming a second metal alloy layer of the turbomachine component on the first metal alloy layer, and binding the first metal alloy layer with the second metal alloy layer.
