Influence of Sol-Gel coatings on the corrosion behaviour of MgZn1 foams with 30 % porosity

The aim of this study was to investigate the ion release behaviour of MgZn1 foam with 30 % porosity and three different sol-gel coatings by static immersion test. Compared to uncoated samples the corrosion could be reduced significantly with all three coatings. Under these test conditions Coating 1 revealed the best corrosion protection.
