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.
