Abstract
The mechanism of corrosion inhibition has been studied for an Al‐Si‐Mg alloy in a 0.1 N NaOH medium at 60 °C with cheap, non toxic substances. The effects of Ca^2+^ and tartrate ions are differentiated and the presence of an insoluble calcium alumino tartrate is evidenced. The greater stability of an amorphous alumino silicate phase is also emphasized, and with electrochemical measurements, weighing tests, X‐ray diagrams and IR spectroscopy, the importance of Al^III^ is revealed.
