Beschreibung
Zusammenfassung:	The invention discloses a method for cladding a nano Fe-Al mixed powder alloy layer on an aluminum alloy surface by high-energy electron beam heating, which comprising the following steps of: (1) dissolving nano Fe-Al powder mixture into plaster with absolute ethyl alcohol and spreading on the aluminum alloy surface; (2) heating for drying; and then pressurizing by using a pressurizer to form a 0.2-0.3 mm film layer on the aluminum alloy surface; and (3) heating by using electron beams in a vacuum chamber to form a nano alloy layer on the aluminum alloy surface. The invention has the advantages that no oxidation, simple method, convenient operation and high efficiency are achieved since the heating treatment is conducted in the vacuum chamber; in addition, a nano alloy strengthening layer obtained by the method has high strength and hardness, good abrasion resistance, corrosion resistance and high temperature resistance.
