Korrosionsverhalten binärer Magnesium‐Zink‐Legierungen in salzhaltigen Medien

Aluminum is a prevalent alloying element to improve the corrosion resistance of magnesium alloys. Recent investigations found out that alloying small amounts of zinc can decrease the corrosion rate of binary magnesium‐zinc alloys. Based on these results low‐alloyed MgZn‐alloys have been analyzed in gravimetric and electrochemical measurements using varied chloride containing media. It was detected that small amounts of zinc have positive effects on the corrosion behavior; in low as well as high concentrated sodium chloride solutions. The overall tendencies of the results from the gravimetric and electrochemical investigations can be correlated. This was underlined using micro‐tomography analyses.
