Abstract: PURPOSE: An apparatus and method for forming an alloy material using a spray forming method are provided to efficiently prevent the oxidation of metal and to form the alloy material in which at least two substances are uniformly mixed. CONSTITUTION: An apparatus for forming an alloy material using a spray forming method includes a molten metal generating part (10), a spray chamber (50), a gas jetting part, and a substrate (51). The molten generating part has a melting chamber and a heating unit. The melting chamber has a closed inner space, and the heating unit melts an ingot charged into the melting chamber. The spray chamber is installed at the lower side of the melting chamber. The gas jetting part jets inert gas to molten metal, which is discharged from the melting chamber and falls into the spray chamber, and then granulates the molten metal into droplets. The droplets falls and are laminated on the substrate.
