Abstract
An automotive component () is manufactured by depositing a non-metallic coating () on a surface of a steel blank () before hot stamping the steel blank (). The non-metallic coating () is typically applied by physical vapor deposition. The non-metallic coating () is formed of one to three layers () each having a different composition. The non-metallic coating () includes at least one of silicon and carbon, and can also include oxygen, nitrogen, ceramic compounds, and carbides. The total thickness of the non-metallic coating () is less than 300 nm. A metallic coating () can be applied to the steel blank before the non-metallic coating (). The non-metallic coating () provides numerous advantages, including reduced scaling during the hot stamping process.
