Corrosion Resistance of Mechanically Activated Alloys in the Al–Cu–Fe System Containing Icosahedral Quasi-Crystalline Phases in Acidic Media
摘要
Abstract
The electrochemical behavior of two single-phase alloys in the Al–Cu–Fe system prepared by mechanical activation is studied in acidic media using potentiodymanic measurements. The first alloy is crystalline and consists of the β-Al(CuFe) phase; the second alloy consists of a quasi-crystalline icosahedral phase. The second alloy with the quasi-crystalline icosahedral structure is more stable. The corrosion stability of samples decreases with a decrease in the solution pH.
