NaCl-Induced Atmospheric Corrosion of the MgAl Alloy AM50-The Influence of CO2
Source abstract
Abstract
The NaCl-induced atmospheric corrosion of the MgAl alloy AM50 has been investigated using 99.97% Mg as reference. Polished samples were exposed up to 672 h in 95.0% RH air with 400 ppm or 0 ppm CO 2 at 22.00°C. Samples were analyzed gravimetrically and by SEM/EDX, XRD and XPS. CO 2 inhibited atmospheric corrosion with alloy AM50 corroding 6–7 times faster in the absence of CO 2 . Brucite and meixnerite (Mg 6 Al 2 (OH) 18 × 4.5H 2 O) formed in the absence of CO 2 . In the presence of CO 2 and NaCl three magnesium-hydroxy-carbonates, giorgiosite, hydromagnesite and Mg 5 (CO 3 ) 4 (OH) 2 × 8H 2 O formed. The influence of CO 2 on the electrochemical corrosion process is discussed.
