Automotive Components non-metallic coating is made of a thin metal plate that has been coated

摘要

An object of the present invention is to provide a process for the production of automotive components and the automotive components consisting of a heat-formed steel It is in. A steel blank (26) before hot stamping, automotive components which are produced by depositing a non-metal coating (24) on the surface of the steel blank (20). Non-metal coatings are typically applied by physical vapor deposition. Non-metal coating is formed from layers 1-3 having different compositions (32). Non-metal coating comprises at least one of silicon and carbon, more oxygen, nitrogen, can include ceramic compounds, and carbides. The total thickness of non-metallic coating is 300nm smaller. Prior to application of the non-metal coating, it is also possible to apply the metal coating (30) to the steel blank. Non-metal coatings, many advantages, including a reduction of scaling during hot stamping is obtained.BACKGROUND 1
