Sputter-deposited Mg–Al–Zn–Cr alloys – Electrochemical characterization of single films and multilayer protection of AZ31 magnesium alloy
Source abstract
Abstract
Abstract Mg–Al–Zn–Cr alloy films were deposited on glass and AZ31 substrates by dc magnetron sputtering in a wide range of Cr concentrations. Distinctive passive regions and breakdown potentials identified high passivity when Cr concentrations were over 30 at.%. Both single and multilayer structures did not show any protective effect on the AZ31 magnesium alloy. SEM revealed a distinctive corrosion activity along the AZ31–alloy interface leading to delaminating of the alloy film. A high protection performance of AZ31 was achieved when applying annealed multilayer structures. The research proposes a concept of magnesium protection by Mg alloys with resistant metals, which do not form intermetallic compounds with Mg.
