Corrosion-resistant aluminum alloy plate and processing technology thereof

The invention relates to the technical field of aluminum alloy plates, in particular to a corrosion-resistant aluminum alloy plate and a processing technology thereof. According to the scheme, an aluminum alloy base plate serves as a base material, a film layer is deposited on the surface of the aluminum alloy base plate in a sputtering mode so as to improve the corrosion resistance and the wear resistance of the aluminum alloy plate, the aluminum alloy base plate comprises, by mass, 5.85%-6.42% of Zn, 2.2%-2.3% of Mg, 2.13%-2.18% of Cu, 0.05%-0.055% of Fe, 0.02%-0.041% of Si, 0.01%-0.019% of Mn, 0.094%-0.12% of Zr, 0.003%-0.01% of Cr and the balance Al and inevitable impurities, and the aluminum alloy base plate formed through machining according to the formula has the advantages that the corrosion resistance and the wear resistance of the aluminum alloy plate are improved; the composite material has excellent mechanical properties and is suitable for scheme implementation. According to the method, the sputt
