PROCESS FOR PROTECTING VEHICLE BODY COMPONENTS, CHASSIS COMPONENTS, ENGINE COMPONENTS OR EXHAUST SYSTEMS FROM CORROSION

摘要

The invention relates to a process for protecting vehicle body components, chassis components, engine components or exhaust systems from corrosion. In order to provide a process for actively protecting vehicle body components, chassis components, engine components or exhaust systems from corrosion, in which case the layer is to be applied on an industrial scale to standard steel and to sand-blasted press-hardened parts using conventional means (e.g. dipping, spraying, flooding), the invention proposes a process comprising the following process steps: a. using steel alloys which are conventionally used in the construction of vehicle bodies and vehicles or using hot-formed or press-hardened vehicle body components, chassis components, engine components or parts of exhaust systems which are provided with metallic coatings or metal-pigment-containing coatings or with such coatings for protection against scaling, b. using conventional joining processes to join together at least two vehicle body components, chassis components, engine components or parts of exhaust systems, which differ in composition, process undergone or surface coating, to form a composite, wherein at least one of the components joined together to form the composite is a hot-formed or press-hardened component, c. applying an anti-corrosion coating to the composite.
