Abstract / Full Text

The electrochemical behavior of three alloys of different composition in the system Al65Cu25Fe10 – хCrх is studied by the potentiodynamic method in alkaline and neutral media as a function of the number of quasi-crystalline phases. The chromium-containing alloys characterized by the presence of the quasi-crystalline (decagonal and icosahedral) components demonstrate the highest stability. It is shown that as the solution pH increases, the corrosion stability of samples decreases.
