摘要： Arrangement (1) for decreasing galvanic corrosion between metal components that includes at least a first component (2) in which a first metal is a part, and at least a second component (3) in which a second metal is a part, whereby the first metal has a higher normal-electrode potential (e0) than the second metal. The first component (2) is intended, after mounting, to be in electrical contact with the second component (3). The first component (2) is coated with a substantially continuous surface layer (4) that is adjusted to give the second component (3) an insignificant galvanic corrosion velocity after mounting. The invention is preferably applied in association with attachment elements such as bolt or screw joint reinforcements, which include a more noble metal than the component or the components with which the attachment element should be in contact with after mounting, and is particularly, preferred for vehicle components.
