METHOD FOR INCREASING THE CORROSION RESISTANCE OF A COMPONENT FORMED OF A MAGNESIUM-BASED ALLOY AGAINST GALVANIC CORROSION, AND CORROSION-RESISTANT COMPONENT OBTAINABLE BY SAID METHOD

摘要

The invention relates to a method for increasing the corrosion resistance of a component formed of a magnesium-based alloy against galvanic corrosion, in particular micro-galvanic corrosion. According to invention, an increase in the corrosion resistance against galvanic corrosion is achieved in a simple manner in that a surface layer of the component having a predefined thickness, which surface layer is formed of the magnesium-based alloy, is heated such that the surface layer has a homogenized mixed-crystal phase, whereupon the surface layer is cooled such that the surface layer has a supersaturated mixed-crystal phase. The invention further relates to a corrosion-resistance component obtainable by a method of this type.
