Fabrication of NiAl strengthened Cu-Al based composite

Modern technologies require constant and frequent improvement of materials for specialized applications. Nickel aluminum and its composites are one such material with distinctive properties that make them particularly suitable for high temperature applications, especially in the aerospace industry. Alloys of the Cu-Al system are corrosion resistant and are a common material for tribological applications. The formation process and technological features of the production of a composite material based on an industrial Cu-Al alloy by the method of electron-beam additive surfacing are considered in this work by the methods of electron microscopy. Production was carried out by combining wire and powder methods of material feeding. By selecting the printing parameters, it was possible to obtain a material with a uniform distribution of the strengthening NiAl phase.
