abstract |
The present invention relates to a novel corrosion inhibitor composition for magnesium or magnesium alloys and to a method for inhibiting corrosion of such metals using the composition. The corrosion inhibitor composition includes a compound containing a carboxyl group to prevent re-precipitation of noble metal impurities, thereby significantly reducing the corrosion rate by complexing the noble metal impurities, such as iron, nickel and copper. |
