摘要：

Corrosion of AlCu-xSn alloys was investigated at 0, 0.1, 0.2 and 0.5 % H2O2 concentration in deionized water at neutral pH. The aim of this work was to study the effect of Sn concentration in alloy on its dynamic corrosion in the presence of H2O2 oxidizer. The concentration of Sn in the alloy was 0%, 1%, 2% and 3%. Potentiodynamic polarization of the alloys in different concentration of H2O2 was obtained to understand their electrochemical behavior. The dynamic corrosion tests were conducted by immersing the samples in beakers on a magnetic stirrer. The corrosion rates were calculated via weight loss measurements. The corrosion rates obtained show an increase with 1% Sn in the alloy as compared to Sn free AlCu. However, beyond 1% till 3% an almost linear decrease in corrosion rates have been observed. The samples had the surface roughness before corrosion tests however after the tests the roughness values show the same trend as corrosion behavior which can be attributed to their wettability behavior. © 2020, Cefin Publishing House.
