A method for protection against and galvanic corrosion for a magnesium - or magnesium alloy - component and a magnesium - or magnesium alloy - component produced according to the method

摘要

Method for providing a protection against galvanic corrosion for a magnesium - or magnesium alloy - component (12) by means of an insulating body (14), the relative to the magnesium - or magnesium alloy - component (12) is at the cathode and at least a first surface (18) as well as at least one second surface (16), said method comprising the steps of:(a) a preformed insulating body (14) against galvanic corrosion is provided; and(b) the magnesium - or magnesium alloy - component (12) in position by a section of the insulating body (14) is cast around the galvanic corrosion, and indeed so that the at least a first surface (18)of the insulating body (14) in a galvanic corrosion in position cast, metallurgically connected relationship at least partially within the magnesium - or magnesium alloy - component (12) is fastened;characterized in thatthe magnesium - or magnesium alloy - component (12) in position a further embodiment of the section of the insulating body (14) against galvanic corrosion is cast around that the second surface (16) of the insulating body (14) in part, a surface of the magnesium - or magnesium alloy - component (12) and a contact with a surface of the magnesium - or magnesium alloy - component (12) forms,n="9"wherein the first surface (18) at least one leg portion (18) in the magnesium - or magnesium alloy - component (12) projects,wherein the second surface (16) as a front plate section (16) is designed.
