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 a process for producing a coating on the surface of a substrate by plasma-electrolytic oxidation. Improved corrosion protection for lightweight metals, in particular for magnesium or magnesium alloys, is achieved by the process. Furthermore, biocompatible protective layers can also be produced on these materials, with the option of controlling degradation of the substrate. The layers are amorphous. They are produced by plasma-electrolytic oxidation in which the substrate is dipped as electrode together with a counterelectrode into an electrolyte liquid and a sufficient electric potential for generating spark discharges at the surface of the substrate is applied, wherein the electrolyte comprises clay particles dispersed therein. Substrates can therefore be any machine components, automobile components, railroad components, aircraft components, ships' components, etc.

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.

Abstract: The present invention relates to a corrosion resistant magnesium alloy which can be prepared with a justifiable expenditure of energy from scrap or impure copper containing precursors and displays a ductility such that it can be used as a casting or kneading material. The magnesium alloy contains, relative to the total weight of the magnesium alloy, 1 to 9 wt. % aluminium, 0.6 to 6 wt. % zinc, 0.1 to 2 wt. % manganese, 0 to 2 wt. % rare earth elements, 0.5 to 2 wt. % copper, wherein the weight ratio of aluminium to zinc lies in the range from 1:1 to 2:1.

Abstract: A part containing magnesium is coated by wetting the part with a polymer solution that contains polyetherimide and a solvent to provide a wetted part; and drying the wetted part to form a coating layer on the part. The corrosion rate of a biocomponent made of magnesium or a magnesium alloy is controlled by forming a coating layer on the biocomponent according to a method described herein, wherein the coating layer has a porosity that provides a corresponding corrosion rate.

Abstract: The invention relates to the development of a corrosion-resistant magnesium secondary alloy. In the field of magnesium metallurgy, no secondary alloys have existed so far such as they exist in the case of other metals such as aluminium, for example. Magnesium alloys are corrosion-resistant if the copper, nickel and iron contents are very low. Recycling of old scrap metal with the aim of again producing structural parts has therefore not been possible up till now since too much copper and nickel are contained in this scrap metal According to the invention, this problem is solved by a new magnesium secondary alloy having been developed which, in spite of higher contents of copper, nickel, iron and silicon, possesses the same corrosion properties as pure magnesium alloys.
