摘要：
The electrochemical behavior of five alloys of variable compositions in the Al65Cu25Fe10-N... Cr (N...) system in dependence on the number of QC phases in acidic and alkaline media has been investigated by the potentiodynamic method. It has been established that the samples' corrosion stabilities increase along with the increase of the solution pH. Higher stability was manifested by alloys with a predominant quasi-crystalline (dexagonal and icosahedral) structural component.
