Vehicle body components with a metal hybrid construction and production methods for such vehicle body components

摘要

Method for manufacturing a zinc-coated nonferrous metal component for the production of a corrosion-protected vehicle body in a mixed construction includes providing an untreated nonferrous metal component and applying a coating by zinc diffusion onto the nonferrous metal component. A zinc dust mixture is diffused at a temperature of from 300 to 600° C. so as to form a zinc diffusion layer.

1. A method for manufacturing a zinc-coated light nonferrous metal component for the production of a corrosion-protected vehicle body in a mixed construction of a light nonferrous metal component and a steel component, the method comprising:
providing a light nonferrous metal component which has not been treated; and applying a coating by a zinc diffusion onto the light nonferrous metal component by diffusing thereon a zinc dust mixture at a temperature of from 300 to 600° C. so as to form a zinc diffusion layer as the coating, thereby providing the zinc-coated light nonferrous metal component, wherein, the coating prevents an immediate contact between the light nonferrous metal component and the steel component in a joining region, and wherein, the light nonferrous metal component is titanium or a light metal alloy on the basis of titanium.
