Purpose - The purpose of this paper is to prepare the Mn-Si-Fe-Cu-Al alloy explosion suppression materials, and determine the corrosion behavior of aluminum alloy explosion suppression materials in HCl and NaOH solutions. The different mechanism of corrosion was discussed. Design/methodology/approach - In this paper, Mn-Si-Fe-Cu-Al alloy explosion suppression materials were prepared; and the electrochemical behavior of the EAESM was studied. The corrosion parameters were calculated and the mechanism of the corrosion process was discussed. The corrosion behavior was characterized by immersion tests and SEM at room temperature. Findings - Mn-Si-Fe-Cu-Al alloy explosion suppression materials have been prepared. SEM, the polarization curves showed that materials have corrosion resistance. The best content of Al alloy is Mn 0.880%, Si 0.135%, Fe 0.383% and Cu 0.0835%. Originality/value - The results of this investigation show that adding alloying elements can form new strengthening phases that influence the corrosion resistance of alloys. |
