摘要：

In order to prepare aluminum alloy explosion suppression materials with good corrosion resistance, four kinds of aluminum alloy foil with different components were synthesized. The corrosion behaviors and surface corrosion morphologies of the aluminum alloys foils in HCl solution were determined by chemical corrosion tests and scanning electron microscopy (SEM). The corrosion rates were determined by weight loss method, the potentiodynamic polarization curve parameters were analyzed, and the influences of alloying elements on the corrosion resistance properties of aluminum alloy foils were systematically analyzed. The results showed that corrosion tests and potentiodynamic polarization measurements were in accordance with each other when evaluating the corrosion rate of aluminum alloy foils. The transition elements could improve the corrosion resistance of aluminum alloy foils effectively by forming different strengthening phases. The influence mechanism of alloying elements on corrosion resistance of aluminum alloy was discussed. Comprehensive analysis showed that the aluminum alloy foil with 1.15% Mn, 0.30% Si, 0.46% Fe, 0.16% Cu, 0.05% Zn, 0.05% Ti, 0.05% Cr (mass fraction) displaying a better general corrosion resistance in acidic conditions, could be used as explosion suppression material.
