Abstract: The present invention relates to electrolyte additives for magnesium air batteries, which are compatible with rechargeable magnesium batteries and carry the promise of overcoming the hurdles, especially enhancing the overall performance of magnesium air batteries comprising an aqueous electrolyte. The electrolyte additive for a magnesium battery comprising a chelating agent which is capable of forming a complex with at least one of Fe(II), and Fe(III) ions, where the complex with at least one of Fe(II) and Fe(III) ions has a stability constant in aqueous solution at room temperature (about 25° C.) log K of greater than or equal to 6.0 and which is also capable of forming a complex with Mg(II) ions where the complex with Mg(II) ions has a stability constant in aqueous solution at room temperature (about 25° C.) log K of greater than or equal to 4.0.

Abstract: The present invention relates to novel corrosion inhibitor compositions for magnesium or magnesium alloys and to a process for inhibiting the corrosion of such metals using such compositions. The corrosion inhibitor composition for magnesium or magnesium alloys comprises at least one corrosion inhibiting compound which is capable of forming a complex with at least one of Fe(II), Fe(III), Cu(I), Cu(II) and Ni(II) ions, where the complex with at least one of Fe(II), Fe(III), Cu(I), Cu(II) and Ni(II) ions has a stability constant in aqueous solution at room temperature (about 21° C.) log K of greater than or equal to 3.5 wherein the corrosion inhibiting compound is selected from the group of pyridinedicarboxylic acids, and their salts or esters thereof.

Abstract: The present invention relates to novel corrosion inhibitor compositions for magnesium or magnesium alloys and to a process for inhibiting the corrosion of such metals using such compositions. The corrosion inhibitor composition comprises a compound comprising a carboxyl group preventing the re-deposition of noble impurities which significantly decreases the corrosion rate by complexing said noble impurities, e.g. iron, nickel and copper.

Abstract: The present invention relates to magnesium components with improved corrosion protection. The components are coated with a vitreous binary Mg—X alloy or a vitreous ternary Mg—X—Y alloy, where X is an element selected from the group consisting of the elements of main group III, of transition group III or rare earth elements of the Periodic Table of the Elements, and Y is an element selected from the group consisting of the elements of main group III or IV, of transition group III or IV or rare earth elements of the Periodic Table of the Elements. The coating is produced by means of physical vapor deposition processes, such as cathode ray atomization.
